The lithio derivative of phenyl trimethylsilylmethyl sulfide undergoes smooth addition to activated ethylene derivatives to afford trimethylsilylcyclopropanes, except for the addition to methyl 2-phenylpropenoate which leads to the formation of methyl 4-trimethylsilyl-2-phenyl-4-(phenylthio)butanoate.
