The authors indicate this text is d e signed for students "desiring a oneyear exposure to the field of chemistry to prepare them for other professions or to increase their knowledge and understanding of current developments in chemical research." They planned to "include a. balance between a brief historical development, the essential d e scriptive material, and the mechanism of chemicd reactions in general, organic, and biological chemistry" and offer the hook as s survey of these fields. Any attempt to follow as hroad a program as the authors suggest would doubtless invite criticism a t every tumchoice of topics covered, depth of coverage, too much or too little mechanism, d e scription, and theory. To focus on one small point, for example, one finds in the only chrtpter on metals covering all representative and transition metals complete with coordination compounds that in the total of twenty-seven pages about five of them are devoted to iron metallurgy with blast furnace, Bessemer, and open hearth processes all intact. Certainly a trained chemist going through a book like this as his eye catches flashes of term after t e r n will probably subconsciously add his own understanding of them.

Although substantive changes have been made, essentially all of the attractive features of the first edition [see DENO,N. C., J. CHEMEDUC.,42, 177 (1965)l have been maintained and. strengthened.

Among the key pedagogical strengths of the first edition were its clear style of presentation, its emphasis on direct data as a. means of generating intellectual models, and its pioneering attempt to soundly implant spectroscopic methods in the first organic course. These features are salient attractions of the second edition. In addition ta the stsndard material, expected in nearly all rwsilable modern organic chemistry texts, chapters on Enaymatic Processes and Metabolism, Heterocyclic Chemistry, Photochemistry, Polymers, and Cyclization Resctions offer a well selected group of topics not necessarily given satisfactory coverage in many other texts. In the reviewer's opinion, this text stands along with Morrison and Boyd's "Organic Chemistry" and Hendrickson, Cram, and Hammond's "Organic Chemistry" a? the outstanding texts for the first year Organic course. Roberts and Caseria's text stands close to Morrison and Boyd's text in terms of the more traditional "functional group" sppraach. The Roberts and Caserio text probably has a. stronger theoretical flavor than that of Morrison and Boyd, with the latter emphasizing comprehensiveness of reactions, more than Roberts and Caserio. Hendrickson, Cram, and Hsmmond's text is excellent in many respects, but many instructors may prefer to use it as a supplemental text rather than the main text, because of its strong organization structured about theory. Although the latter is an intellectually exciting and gratifying approach, it may he beyond the ability of many students, especislly those who take organic chemistry without s. strong proclivity for, or background in science. An instructor who anticipates adoption of an organic text will certainly want to inspect all three texts mentioned above before decidingon a find selection. Few criticisms can be leveled a t Roberts and Caserio's text, which must be considered as an important and timely contnhution to education in chemistry. A couple of minor points are: the presentation of ir and nmr spectra might be improved by (a) not breaking the ir spectra into two pieces (an idiosyncrasy of the particular machine employed hut which may confuse students into thinking it is important); (b) not hrwing intenseir pezks go off scale, since thisdistorts the inexperienced viewer'sperspective of "intense," "moderate," and "weak" hands; (c) although a very pretty discussion of spin-spin splitting is given in Chapter 7, the concept is

not used that much later on, especially relative to the concept of chemical shift (which the reviewer feels should be expanded substantially); ( d ) the nmr spectra should have a, uniform vertical scale, so that the inexperienced eye immediately associates relative peak position with chemical shifts. Finally little space is given to the new concepts of orbital symmetry control of certain organic reactions.

The purported primary objective of this hook is to provide undergraduate students with a dear, concise guide to the im~ortant general reactions o? organic chemistry. I t is intended as a supplement to campensate for the increased emphasis an theoretical and physical concepts in modern organic texts. To this end the author has succeeded admirably. However, one may question the universal need for such a supplement as a t least one of the most papular organic texts does, in this reviewer's opinion, an adequate job of summarizing the important preparations and reactions of the various classes of compounds. The book emphasizes the reactions used in the synthesis of a particular class of compounds rather than the rertctions which a class csn undergo, although these are summarized for all the important categories of compounds. The survey is quite complete, covering 48 classes of compounds with all the important, widely applicable syntheses included as well as many less common reactions. Reaction mechanisms are not discussed in any detail although reaction intermediates are shown in some instances. Each reaction is. written in general form followed by a brief (typically 50 words in length) discussion concerning its scope and synthetic usefulness; this particular feature is extremely heneficid and is probably the chief merit of the hook. Following the discussion, each general resotion is further illustrated by a. specific example. The only references cited are those to Organic Syntheses from which mmy of the examples have been taken. Although this is probably of little concern to the undergraduate student, it ma" he viewed as s. slieht disadvantaee if the hook i* utilized in .ilr.onlnnr~with the expec.t~tiot,sof the author n, n refrrenve and review guide to those who have completed their formal training in organic chemistry.

organic or organometallic chemistry who wishes to enhance his understanding of certain principles peculiar to metal rcomplex chemistry. Other published books on organometallic chemistry either cover the field as a whole (eg., Coates, Green, and Wade), the whole area of transition-metal organometallio chemistry (e.g., King), or more specialised areas such as metal bensenoid complexes (Zeiss) or the iron group metallocenes (1Losenblum). This book is divided into seven chapters organized according to general topics in metal rr-complex chemistry. There are exercises st the end of each chapter. This feature makes the hook more useful for students. There is also a bibliography a t the end of each chapter, but this bihliography is limited to several general references. An introductory hook of this type would be much more useful if it provided a more extensive bibliography so that the reader with interest in exploring a topic in greater detail could be directed immediately to relevant journal articles. The fint chapter in this book discusses organometallic nomenclature but the names presented are not particularly systematic. Furthermore, Cotton's "hapto" system of nomenclsture is not mentioned. I feel that if nomenclature is specific&lly discussed, Cotton's system should also be discussed since it provides more definitive names for many of the complexes discussed. However, I feel that this chapter could easily have been eliminated and the space so relewd used for a better bibliography.

The second chapter discusses the p r e p arations of metd r-complexes. The classification of the preparative techniques is not particularly logical and the order irrational. Furthermore, eqn. 2-6 is wrong since Fischer and co-workers have shown that the benzene solvent rather than the benzene in the dibensenechromium is the source of the benzene ring in benzenetrioarbonylchromium. Other errors in this 5 chapter include depicting ( C . H S ) ~ Ma~ covalent rather than ionic (p. 23, eqn. 2 3 4 ) and the mysterious species "iron monocarbonyl" (p. 25). The third chapter discusses bonding in r-complexes. The clarity and conciseness of the ideas presented in this chapter leave much to be desired. The diagrams on pp. 30 and 31 are unnecessary since the points could be demonstrated more easily and concisely by simple electron counting. The diagrams on pp. 34 through 39 will unnecessarily ,confuse many readers. "Stibines" are erroneo~dycalled "stilhenes" on p. 44. The fourth chapter on spectroscopic and magnetic properties of metal r-complexes is probably the most useful chapter in the book. The szctions on infrared and nmr are generally well-written hot the section on mass spectroscopy is too brief m d sketchy to he of muoh use. The section on magnetochemistry does not mention the Fmaday method, an important technique for measuring the magnetic swceptibilities of organometallic compounds. The section on Mossbauer spectroscopy mentions "quadruple splitting" (p. 83) rather then "quadrupole splitting!'

Cyclohutadieneiron tricarbonyl is a poor example to use in the mass spectroscopy section since the reported fragmentation behavior is doubtful. The fifth chapter on structure and structure determination gives specific examples of key structures in metal rcomplex chemistry and the techniques, including X-ray ccrystallogrsphy, by which they were established. The examples are not presented in a logical order. Some figures are very poorly drawn (e.g., figures (5-I), (5-17), (.&18), and (5-19)). The nmr chemical shift scale used for the 16.8 cps peak of CsHsFe(CO)son p. 105 is not specified. The sixth chapter on reactions of metd rr-complexes provides a useful summary of much of their chemistry. Again this chapter contains some erroneous information notably eqn. 6-39 on p. 142, the discussion on the nmr of C,H,V(CO)8 on pp. 156 and 157, and the mention of the "cyclobutadiene-silver nitrite" complex on p. 162. The seventh and find chapter discusses catalysis involving metd r-complex intermediates. This chapter is a useful summary of an important area. of applications of metal r-complexes. In summary, I do not rate this book very high because of poor organization in some chapters and numerous errors as exemplified above. In addition, the number of typographical errors seems excessive particularly for a book costing 7 cents 5 (Catinued m page A606)
