Article abstract of DOI:10.1016/S0040-4039(98)80054-3

The thermal conversion of sulfoxide 1 into the O-silylated cyclic O,S- acetal (2) is the first example of the sila-Pummerer rearrangement of cyclic organosilicon sulfoxides leading to ring expansion. The kinetics of the rearrangement are studied and thermodynamic parameters are determined. The results are in compliance with mechanism involving a pentacoordinated silicon atom.
