Abstract
The reactions of sulfonamidation of functionally substituted vinylsilanes having Si–Ph, Si–Cl or Si–O bonds (triphenylvinylsilane, trimethoxy(vinyl)silane, trichlorovinylsilane, dichloromethylvinylsilane, tris(2-methoxyethoxy)vinylsilane) with trifluoromethanesulfonamide, arenesulfonamides and methanesulfonamide in the presence of (t-BuOCl + NaI) or N-bromosuccinimide proceed in different manner depending on the substrate, reagent, and oxidant. The formation of the products of halosulfonamidation, heterocyclization, halogenation, solvent interception and desilylation is observed.
