The reaction of benzamide with thionyl chloride in the presence of pyridine gave N-sulfinylbenzamide and N,N′-dibenzoylsulfurdiimide. It has been found that N-sulfinylbenzamide reacted with styreneoxide in the presence of tetraethylammonium bromide to give 4-oxo-5-benzoyl-2,6-diphenyl-1,4,3,5-oxathiadiazepine as the main product, accompanied by lesser quantities of two N-benzoyl-phenylaminoethanols

Treatment of amine derivatives such as amines, sulfonamides, and amides with N,N′-sulfinylbisimidazole and N-(chlorosulfinyl)imidazole respectively gives the corresponding N-sulfinylamine derivatives (); the latter reaction using N-(chlorosulfinyl)imidazole yields in almost quantitative yields at 20°C under mild conditions.
cascade O-sulfination and desulfurdioxidative N−N coupling (via stepwise retro-[2π+2σ] cycloaddition, supported by quantum chemistry calculations) from readily available N-arylhydroxylamines and N-sulfinylanilines under metal and oxidant free conditions.
