Ferrocenesulfonyl azide reacts with a number of aroylmethylenetriphenylphosphinomethylenes in dry methylene chloride to give 1,4,5-trisubstituted 1,2,3-triazoles (61-77percent yields), which are readily converted to 4,5-disubstituted 1,2,3-triazoles and ethyl ferrocenesulfonate when they are refluxed in ethanol.The known triphenylphosphazo ferrocenyl sulfone and ethyl diazoacetate are formed in the case of the reaction of ferrocenesulfonyl azide with carbethoxymethylenetriphenylphosphinomethylene.The structures of the synthesized compounds were proved by the results of elementary analysis and IR, UV, and mass spectroscopy.
