Abstract

The compound R2C(SiMe2OMe)(SiMe2Cl) (R = SiMe3 throughout) reacts more rapidly with CF3CH 2OH than with MeOH, and R2C(SiMe2OMe)(SiPh 2Br) reacts with EtOH to give exclusively the rearranged product R2C(SiMe2OEt)(SiPh2OMe), indicating that the rate-determining step of the solvolyses involves formation of a methoxy-bridged cation; migration of the OMe group also occurs in the reaction of the bromide with AgBF4.
