Expedient Acylations of Primary and Secondary Alkyl Cyanides to α-Substituted β-Ketonitriles
摘要:
Primary and secondary cyanides are efficiently acylated with N-acylbenzotriazoles 3a-f (derived from a variety of acids) to afford the corresponding alpha-substituted beta-ketonitriles 5a-r in 67-96% yields.

Base-free catalytic alpha-alkylation of active methylene compounds with primary alcohols was successfully achieved using an [IrCl(cod)](2) complex in the presence of PPh(3) to afford the corresponding saturated alpha-alkylated products in good yields.
