Abstract: The substituted vinylphosphonium salts of the general formula RCCl=C(N=CClAr)P(+)Ph(3) Cl- react with an excess of sodium azide in a peculiar manner. As a result, phosphonium ylides are produced. They are stabilized with a nitrile and a 5-aryltetrazol-1-yl group or with two substituted tetrazolyl residues as confirmed by X-ray structural analysis. All the ylides obtained exhibit low reactivity and do not enter into the Wittig reaction, but one of them was found to undergo the following sequence of transformations: N drop C-C=P- --> H2N-CO-C=P- --> -P=N-CO-CH2-.
