Olah receives Baekeland Award Work in carbonium ions and other diversified research earn recognition by ACS North Jersey section Few developments in organic chemistry in the past decade can rival in impact the discovery that carbonium ions can be stabilized and studied as distinct species in solution. And no man, one colleague says, has done more to put this field of intense interest and major importance on a firm footing than Dr. George A. Olah, recipient of the 12th Leo Hendrik Baekeland Award of the ACS North Jersey Section. In addition to his work on carbonium ions, Dr. Olah was cited for "diversified and notable research" in organic compounds of fluorine, phosphorus, and arsenic, and in aromatic substitution and isomerization. The Baekeland Award, a gold medal and $1000, is sponsored by Union Carbide Chemicals & Plastics Co. Dr. Olah is chairman of the department of chemistry at Case Western Reserve University and is one of the world's foremost authorities on Friedel-Crafts reactions. He has edited and contributed to a four-volume monograph on the subject, and is the author of the two-volume text, "Introduction to Theoretical Organic Chemistry." He has published close to 200 technical papers and has 50 patents issued in his name. In addition to ACS, he is a member of the Chemical Society (London), the German Chemical Society, and the Chemical Institute of Canada. He received the 1964 ACS Award in Petroleum Chemistry. Born in Budapest, Hungary, in 1927, Dr. Olah attended the Technical University of Budapest. He did his graduate work in chemistry there under the late Prof. Geza Zemplen, a former student of Emil Fischer and a leading European carbohydrate chemist. After receiving his Ph.D. he became a lecturer and subsequently professor of physical organic chemistry at the Technical University. While still in his 20's he was appointed head of the organic chemistry department and associate scientific director of the newly created Central Research Institute of the Hungarian Academy of Sciences. Dr. Olah left Hungary shortly after the revolution in 1956 in order to find a freer atmosphere for his work. With his family he emigrated to Canada where he joined Dow Chemical's exploratory research laboratory in Sar66 C&EN OCT. 16, 1967
George A. Olah Distinct species
nia, Ont. In 1965 he transferred to Dow's eastern research laboratory at Framingham, Mass. Dr. Olah's early work in Hungary dealt with the synthesis of organic fluorine compounds. Derivatives of some of these compounds, such as fluoroethanol and fluoroethyl amine, were sought for pharmacological testing. Out of this work, other lines of interest soon developed. Aromatic fluorine compounds were synthesized, including nitrated products, which were prepared by new methods using stable nitronium salts as nitrating agents. From this work developed an extensive study of electrophilic, aromatic substitution reactions. Studies also included the preparation of fluorine compounds containing phosphorus. Interest in tri- and pentavalent phosphorus compounds led to similar studies with arsenic. An important segment of Dr. Olah's research at this time was the study of the fluorides of electronegative elements known for their Lewis acid properties. These fluorides were to play a key role in his later work, first as catalysts for aromatic substitutions and later as mediums for the stabilization and study of carbonium ions. Another subject of Dr. Olah's early
work was formyl fluoride, which he showed to be a general formylating agent. He studied other acid fluorides as well and their behavior with Lewis acids. He showed that stable acyl cations could be prepared, and that these reagents substituted aromatics easily. In the course of nuclear magnetic resonance studies on these reagents, he observed that the tertbutyloxocarbonium ion decomposed to a new species by loss of carbon monoxide. The new species was tert-butyl cation, which was stable in strong acids. This marked the first time that such a simple carbonium ion had been prepared other than as a fleeting intermediate in a complex reaction. Dr. Olah's research since then comprises an extensive amplification of this discovery. With this record of research activity behind him, Dr. Olah became restless for new challenges. He decided to return to academic life after serving on visiting professorships at Ohio State in 1963 and University of Heidelberg in 1965. He accepted the post of chairman of the department of chemistry at Western Reserve University in 1965 and set as his immediate goal the expansion of that school's graduate research facilities. Partly in response to his efforts a National Science Foundation "centers of excellence" grant was given jointly to Western Reserve and neighboring Case Institute of Technology in anticipation that the two schools would merge. The merger has since become reality, and Dr. Olah was chosen to head the department of chemistry at Case Western Reserve.

H o w do y o u harness an unstable character like Hydrogen Cyanamide? Here's what we did: we made a clear, aqueous stabilized solution of 5 0 % H 2 NCN —and named it "Cyanamide 5 0 " . It's easy to handle, available in drums and tank trucks, capable of storage under technical supervision. We know of no comparable product on the market today! As you know, hydrogen Cyanamide is an ideal chemical reactant or modifier—ideal because it combines low molecular weight with extremely high reactivity. Cyanamide 50, for example, adds nitrogen to cellulose, protein, and other natural and synthetic polymers...and lends cationic nature to these substances, normally without changing gross physical properties.

Rowlett returns to CAS Main challenges are CA subscription costs, computer handling, abstracting Russell J. Rowlett, Jr., seventh editor in the 60-year history of Chemical Abstracts, is a soft-spoken, frankly speaking, tough-minded V i r g i n i a n qualities he should find occasion to apply in this crucial phase of CA's history. For the output of chemical literature still is curving sharply upward; it should rise about 14% this year over last year's rate. With this continuing burgeoning of verbiage come problems of production costs, data processing machines, and the efficiency of human beings. Dr. Rowlett, who just turned 47, will be in the thick of trying to solve them. He's been on the job now for three months. In general, Dr. Rowlett—an organic chemist by degree—is responsible for the scientific and technical content of all the services that appear in print, Chemical Abstracts and its indexes and the machine-produced journals such as Chemical Titles and Chemical-Biological Activities. H e comes to CAS from the Virginia Institute for Scientific Research, where beginning in 1960, he filled several shoes as the institute's assistant director. There he planned and raised money for a new building, was administrative director of the research laboratories, and managed to direct a little research in his original field, the synthesis of antimalarial compounds. Of direct bearing on this present job, however, was the institute's contract with CAS for studies of improvements for the printed CA subject indexes. W h a t resulted, through Dr. Rowlett's work, is a system of breaking down the very large subject headings into smaller categories. The system of category indexing is being incorporated for about 400 large headings in the Volume 66 index. Scanning the pathways of Dr. Rowlett's diverse career, one finds that his new job marks a return to an old home. Between 1947 and 1952 he was first an assistant editor, then associate editor at CAS for organic indexing and editing. From there he moved to Virginia-Carolina Chemical Corp. for an eight-year series of responsibilities beginning with patent coordinator and culminating in his appointment as director of research and development. "I'm a Virginian," he says, "but it is good to be back in Columbus. In many ways Richmond and Columbus are alike, being politically in tune with each other and having the surrounding 70 C&EN OCT. 16, 1967
countryside so accessible." Dr. Rowlett admits to some standing in the "Byrd Democrat" club whose philosophy is about comparable to a "Columbus Republican." Mrs. Rowlett, an art and music college major, likes to accompany Dr. Rowlett to ACS meetings. She endured many a tour speaker during the four years her husband served in all the elected offices of the ACS Virginia Section. Dr. Rowlett admits that he expects some rough sledding at CAS. "But I'm not the sort of person who settles into a job looking forward to years of routine. "I see my task as one of working with people trying to get our large staff and corps of abstractors to see the main objective and to work together to achieve our goal. It has been difficult to maintain this togetherness, as the numbers of internal and external CAS workers have grown so rapidly. Specialists are important, b u t they must work together as a team." Dr. Rowlett thinks it isn't generally recognized that much of CAS's work with machines is experimental, laying the base for tomorrow's instant retrieval. CAS is aiming at achieving one intellectual effort for directing reported research results into the primary and secondary chemical literature. Such a single operation would involve editing a paper for journal publication and simultaneously preparing the abstract, index entries, and input for machine storage. A very preliminary approach is being made to this end with some current discussions with the ACS primary journal staff. "The subscription cost of CA really does concern the ACS Board of Directors," he says. "The small colleges will have to struggle to afford the $1050 college subscription rate in 1968. T h e Board is doing all it can to find ways to help these institutions get funds for meeting the price, but it is getting more and more difficult." Another crunch facing CAS is the requirement for more and more abstractors. About 3300 are on the rolls now, each producing an annual average of about 50 abstracts, which multiplies out to 165,000 abstracts. But the total number forecast for 1967 is 240,000. CAS's in-house group of 36 full-time abstractors should close that gap this year, b u t the problem is sure to be more acute next year.
Some critics say the entire system needs changing, such as requiring authors to prepare CAS-style abstracts as prerequisites for journal publication. This idea has advanced past the coffee-break discussion stage and an active program is under way with some of the ACS journals, but they represent only about 4% of the entire chemical journal literature. Should CAS limit the number of journals it monitors? At least one parallel publication does. "The trouble with this scheme," Dr. Rowlett answers, "is that anything you delete winds up as criticism of someone's journal. And scientists themselves will tell you they don't want to miss anything in their field. I do think, however, that the increasing costs of publishing journals and producing abstracts will modify the situation." Another problem Dr. Rowlett is giving some thought to is the man-machine relationship at computer-based CAS. The trouble is that machines are rigid, demanding critters, Dr. Rowlett points out, totally unsympathetic over the travails of human error. Add to this the fact that all present computers will be obsolescent in view of the future requirement for many simultaneous searches of the entire chemical literature, and you must begin looking ahead to the next generation of machines and their human ramifications. "All in all, however, I think it's a tremendously exciting time to be at CAS," Dr. Rowlett says after enumerating the challenges. "We're at the forefront of handling great masses of information, solving how it can all be done, and finding ways people can use it and afford it. It's an honor to follow Jay Crane in this job. It's vastly different now, but I count it a real privilege to have known and worked for a man of such imposing stature. I take on his title humbly with pledges to do my best to maintain his extremely high standards."
