Process for preparing silacyclo-hexane compounds

摘要

A process for preparing a silacyclohexane compound of the general formula <CHEM> wherein R and Q are, respectively, defined substituents, which process comprising the steps of converting a compound of the following formula <CHEM> to a halosilacyclohexane of the following formula <CHEM> wherein X is a halogen, reacting the halosilacyclohexane with an alcohol to obtain an alkoxysilacyclohexane of the formula which is equilibrated in steric configuration, and <CHEM> reducing the equilibrated alkoxysilacyclohexane whereby a trans form silacyclohexane compound is predominantly produced.
