new method for preparing α-cyanoacrylates and α-cyanoenones is described. The procedure uses a phosphine-catalyzed α-C addition of cyanide ion, generated in situ from cyanohydrins, to activated alkynes. An unexpected tandem reaction producing benzylidenecyclopentanones is also described. cyanoacrylates - alkynes - catalysis - phosphines
