- Process for preparing sil acyclohexane-based liquid crystal compounds from silacyclohexanone compounds
-
Silacyclohexane-based liquid crystal compounds are prepared from a cyclohexanone compound of the following general formula (I) 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, and also from organolithium reagents, followed by hydrogenolysis or hydrogenation after dehydration, with or without further reaction with organometal reagents, and then to de-silylation and reduction.
