N-Methyl and N-ethyl derivatives of N-(trifluoromethylsulfonyl)-[N′-(trifluoromethylsufonyl)-trifluoromethylsulfoximidoyl] imides 2a,b were prepared by alkylation of bis(trifluoromethylsulfonylimino)trifluoromethanesulfonic acid 1 or its silver salt 1a. It turns out that these imides are strong alkylating agents in spite of the fact that Me (Et) groups are attached to nitrogen atom. The alkylating activity of n-PrI, i-PrI, n-BuI, and n-AmI in the presence of silver salt of bis(trifluoromethylsulfonylimino)trifluoromethanesulfonic acid 1a was investigated.
