Abstract

Aryliminotriphenylphosphoranes reacted with methanesulfonyl, ethanesulfonyl and α- toluenesulfonyl chlorides in the presence of triethylamine to give 1: 2 adducts [α-(N- alkanesulfonyl-N-arylsulfamoyl) alkylidenephosphoranes] and the decomposition products, instead of 1: 1 adducts [α-(N-arylsulfamoyl) alkylidenephosphoranes). They were obtained under ice-cooling, the structure being of betaine type. In the case of methanesulfonyl ...
