One-pot Michael additions/alkylations of diethyl benzylidenemalonate and ethyl (1-methylpropylidene)cyanoacetate (3) with alkali metal cyanide/phase-transfer (PT) catalyst and alkyl halides in halohydrocarbon solvents yield compounds 2a-f and 4a-d, respectively.It is noteworthy that no conversions occur in the total absence of traces of water.Cinnamates and methacrylates can be cyclo-dimerized by the action of solid cyanide/PT catalyst to give compounds 6 or 8, respectively.
