The reaction of a variety of 2-substituted 1-bromo-1-nitroethylenes with triphenylphosphine in benzene or ethyl acetate gave good yields of cyanomethyl(triphenyl)phosphonium salts, which on treatment with base afforded the corresponding ylides. An analogous cyanomethylphosphonate was obtained from a reaction with triethyl phosphite. Three alternative sites of initial attack by phosphine are considered
