Reaction of α-metallated N-acyl-λ5-phosphazenes with aryl cyanides

Metallated N-acyl-λ5-phosphazenes react with aryl cyanide to give imino-λ5-phosphazenes (6) and (7), in which nitrile insertion into the phosphorus-carbon bond of N-acyl-λ-phosphazenes (2) and (3) takes place. Subsequent reactions of the imino- and enamino-N- ethoxycarbonyl-λ5-phosphazenes (7) and (9) afford the phosphine oxide derivatives (13) and (11), through a cyclocondensation and hydrolysis sequence.
