ADDITION OF TRIMETHYLSILYL CYANIDE TO α-SUBSTITUTED KETONES: CATALYSTEFFICIENCY
Greenlee, W. J.,Hangauer, D. G.
, p. 4559 - 4560 (1983)
Addition of trimethylsilyl cyanide to α-substituted ketones is often slow and incomplete when catalyzed by zinc iodide.Use of potassium cyanide/18-crown-6 complex as catalyst is a superior method, providing high yields of adducts.
