A procedure for a Cu-catalyzed hydrocyanation of α-aryl diazoesters using acetone cyanohydrin as a source of hydrogen cyanide is significantly accelerated by addition of trimethylsilyl cyanide (TMSCN) presumably by delivering free cyanide ion in situ. This method provides various types of α-aryl cyanoacetates in good yields under mild conditions.
