Abstract
A silacyclohexane compound of formula (I): ##STR1## wherein R denotes a linear-chain alkyl group, a mono- or di-fluoroalkyl group, a branched-chain alkyl group, an alkoxyalkyl group, or an alkenyl group: at least one of ##STR2## denotes a 1-sila-1,4-cyclohexylene or a 4-sila-1,4-cyclohexylene group whose silicon at position 1 or 4 is H, F, Cl or CH.sub.3, and the other denotes a 1,4-cyclohexylene group, a 1-sila-1,4-cyclohexylene or a 4-sila-1,4-cyclohexylene group whose silicon at position 1 or 4 is H F, Cl or CH.sub.3 ; X denotes a substitutional group at an equatorial position, specifically CN, an alkyl group with its end group replaced by a trifluoromethyl group, an alkoxy group, an alkanoyloxy group, an alkoxycarbonyl group, a linear-chain alkyl group, or an alkoxyalkyl group; Y denotes a group at an axial position, specifically H or CN when Y is connected to a carbon atom in said (B) group or H, F, Cl or CH.sub.3 when Y is connected to a silicon atom in said (B) group.
