Cyclohexanone compounds, process for preparing the same, and processes for preparing silacyclohexane-based liquid crystal compounds from the cyclohexanone compounds

摘要

A cyclohexanone compound of the following general formula (I) is provided wherein Ar represents a phenyl group or a tolyl group, and R represents a phenyl group, a tolyl group, a linear alkyl group having from 1 to 10 carbon atoms, a mono or difluoroalkyl group having from 1 to 10 carbon atoms, a branched alkyl group having from 3 to 8 carbon atoms or an alkoxyalkyl group having from 2 to 7 carbon atoms. The preparation of the cyclohexanone compound is also described along with processes for preparing liquid crystal compounds from the cyclohexanone compound.
