conditions, affording α‐(hetero)arylacetonitriles via one‐pot decarboxylation. Additionally, the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with α‐alkyl‐substituted ethyl cyanoacetates proceeds smoothly at 60 °C, leading to the formation of α‐alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities

Treatment of heteroaryl-aldehydes with diethyl cyanophosphonate in the presence of a catalytic amount of LiCN affords phosphorylated cyanohydrins which are reduced in situ with SmI2 to give heteroaryl-acetonitriles in generally good overall yields (50-100%). The generality of the process is demonstrated. (C) 2003 Published by Elsevier Science Ltd.
