Sniff the sweet smell of success. Aluminum alkyls for fragrances, vitamins and pharmaceuticals. Organoluminum compounds find wide application in the chemical industry. T h e y are used as catalysts for the polymerization and oligomerization of mono-olefins and dienes, as reducing and alkylating reagents, as chemical intermediates for detergents and plasticizers, as well as for other applications. S h o w n below are three specific reactions illustrative of aluminum alkyls' reducing capabilities. To learn more about these reactions as well as other examples of aluminum alkyls in organic reactions
including alkylations, hydrocyanations, and more reductions, write for our new brochure, "The U s e of A l u m i n u m A l k y l s in Organic S y n t h e s i s , , on your c o m p a n y letterhead.

A yield approaching 90% is achieved when D I B A H or TIBA is used in this reduction, utilizing all three groups on aluminum. K. Ziegler et al., Justus Liebigs Ann. Chem. 623,9 (1959).
The reduction of nitriles to aldehydes with D I B A H is reported in a synthesis of vitamin A. Yields of poly conjugated aldehydes are practically quantitative. Philips-Duphar, British Patent 813,517; Chem. Abstr. 53,22068g ( 1959) ; cf. "Ullmann's Encyclopedia of Technical Chemistry", Vol. 18, 1967, p. 232.
Cost-effectiveness of D I B A H is claimed to be superior to that of lithium aluminum hydride in the reduction of steroidal 11-keto
