The unusual reactivity of the mono- and bis- N-(trifluoromethylsulfonyl)-substituted azaanalogs of arenesulfonochlorides
摘要:
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.

reactivity of N-trifyl-substituted sulfimides with respect to electrophilic reagents and increased their stability. Mass spectra of isomeric cyclic organosilicon N-trifluoromethanesulfonyl-substituted sulfimides VII, X, their acyclic analog III, and the product of the decomposition of the latter at the Si-C(S) bond IV were studied. The mechanism of formation of sulfimides in nonaqueous media is discussed

N-(Trifluoromethylsulfonyl)arenesulfonimidoyl chlorides 3a-e and N,N′-bis(trifluoromethylsulfonyl)arenesulfonodiimidoyl chlorides 6a-e are obtained by N,N-dichlorotrifluoromethanesulfonamide oxidative imination of arene sulfonyl chlorides 1a-e and diaryl disulfides 4a-e, respectively. The electron nature of the new substituents possessing high electron-accepting ability is also determined.

Reactions of trifluoromethanesulfonic acid N-(2,2,2-trichloroethylidene)amide with 1,3-dialkyl-5-chloropyrazoles and 1-phenyl-3-methylpyrazole afforded 4-(amidotrichloroethyl)-substituted pyrazole derivatives. 4-Chloropyrazoles were not involved into this process. The structure of compounds synthesized was studied by means of IR and NMR spectroscopy. The presence of intra- and intermolecular hydrogen bonds was revealed by a decrease in the absorption frequencies and a complicated form of ν(NH) and νas(SO2) absorption bands in the IR spectra, and also in splitting of signals in 1H and 13C NMR spectra.
