The reactions of N-(trifluoromethylsulfonyl)arenesulfonimidoyl- and N, N'- bis(trifluoromethylsulfonyl)arenesulfonodiimidoyl chlorides of general formulas Ar-S(0)(=NSO2CF3)Cl (1) and Ar-S(=NSO2CF3)(2)Cl (2) with ammonia have been investigated and found to yield the ammonium salts of [N-(trifluoromethylsulfonyl)arenesulfinylimino]-N' (trifluoromethylsulfonyl)amides. The high oxidative ability of the chlorides (1,2) have been shown. Thus, chlorides (2) react with benzene or trifluoromethylbenzene, to form the chlorobenzene or 3-chloro- trifluoromethylbenzene. The fluorides of the general formulas Ar-S(0)(=NSO2CF3)F and Ar-S(=NSO2CF3)(2)F have been prepared. Their interaction with ammonia leads to the usual formation of corresponding amides. The electron nature of new electron withdrawing substituents have been investigated.
