Abstract
Chiral, nonracemic compounds of the general formula: ##STR1## wherein n=1 or 2, Y is a hydrogen, fluorine, chlorine or bromine atom, R' is an alkyl or alkoxy group having three to fifteen carbons, and R is an alkyl group having three to fifteen carbons, which are useful as ferroelectric liquid crystal components having high polarization are described. Also described are compounds of the same general formula in which X is OH, which are useful as synthetic intermediates in the preparation of the FLC components of the present invention.
