Synthesis of acyclic α- and β-silyl sulfimides

Conversion of acyclic α- and β-silyl sulfides by their treatment with sodium salts of N-chlorosulfonamides into the corresponding previously unknown sulfimides is described. The process is accompanied by a competing reaction resulting in the formation of α- or β-silyl sulfoxides. β-Silyl sulfimide (9b) undergoes thermolysis to generate trimethylvinylsilane.
