Conversion of acyclic alpha- and beta-silyl sulfides by their treatment wit
h sodium salts of N-chlorosulfonamides into the corresponding previously un
known sulfimides is described. The process is accompanied by a competing re
action resulting in the formation of alpha- or beta-silyl sulfoxides. beta-
Silyl sulfimide (9b) undergoes thermolysis to generate trimethylvinylsilane
.
