N-sulfinyl-substituted arylhydrazines from N-sulfinyltrifluoromethansulfonamide
摘要:
Arylhydrazines react with N-sulfinyltrifluoromethanesulfonamide CF3SO2NSO providing N-sulfinylarylhydrazines and trifluoromethanesulfonamide. The discovered reaction is a first example of a transfer of a sulfinyl group from N-sulfinylsulfonamides to hydrazines. The reasons of different hydrolytic stability of CF3SO2NSO and ArNHNSO are discussed.

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.
