A procedure for the Cu-catalyzed hydrocyanation of α-aryl diazoesters has been developed using acetone cyanohydrin as a source of hydrogencyanide (HCN). It was found that the addition of trimethylsilyl cyanide (TMSCN) significantly accelerates the conversion presumably by delivering free cyanide ion in situ, thus producing various types of α-aryl cyanoacetates in high yields under mild conditions
