Abstract
Abstract The reactions of 1,3,5-tris(fluorosulfonyl)benzene 1 with nucleophilic agents were investigated. It was found that morpholine, β,β,β-trifluoroethanol in the presence of triethylamine and sodium azide formed corresponding 1,3,5-trisulfonyl derivatives. In contrast, nucleophiles such as aniline, thiourea, and potassium thiocyanate do not react with compound 1 even in excess and under moderate heating. The conditions for the selective fluorine atom substitution in one SO 2 F group with morpholine, DMAP and aniline in the presence of triethylamine as well as in two SO 2 F groups with DMAP were found. Anionic σ-complex of compound 1 with nitromethane was isolated as individual compound.
