Phenyl cyanophosphide PhPCN- is formed in the ractions of P(CN)2- with phenyllithium and of PhP(CN)2 with CN-, and it may be prepared by nucleophilic degradation of (PhP)5 with ammonium or phosphonium cyanides.With sulfur it yields phenyl cyanodithiophosphinates 4, by alkylation alkyl(phenyl)cyanophosphanes 6 and by hydrolysis of the latter alkyl(phenyl)phosphine oxides 7. - The molecular structure of PhPCN (3c) as determined by X-ray analysis shows an almost planar anion with 102 deg CPC angle.A long PC and short CN bond in the PCN group make PhPCN- appear as "cyanide complex of phenylphosphinidene".
