The title compounds 8 undergo α,γ-reaction with dicarbonyl dichlorides (4, 5), mono- (9) and dicarboximidoyl chlorides (7) and N,N-bis(chloroformyl)amines (12) to give five- and six-membered N-heterocyclic phoshonium salts (1, 3, 6, 10, 14). - The 1,3-dipolar cycloaddition with N-phenylbenzonitrile imide (11) opens the way to a new one-step synthesis of 1,3,4,5-tetraaryl-1,2,4-triazolium salts 17.The structure of pyrrole derivative 2 is elucidated by X-ray analysis.
