Abstract
N-Vinylic phosphazenes 2 are obtained by Staudinger reaction of conjug ated azides 1 and phosphines. Reactions of phosphazenes 2a,b derived f rom triphenylphosphine with carbonyl compounds 3 involve the gamma-car bon atom of the vinyl side chain as nucleophilic center to give monoad ducts 4, while phosphazene derived from diphenylmethylphosphine 2c und ergoes Aza-Wittig reaction with ethyl glyoxalate and leads to the form ation of substituted 2-azadiene 10.
