A process for producing an optically active halogen-containing alcohol having a high optical purity and represented by the following formula [I] ##STR1## wherein R.sup.1 is a halogen substituted alkyl group, R.sup.2 is a group selected from the group consisting of a substituted or unsubstituted alkyl group, alkene group, or alkyne group, and a substituted or unsubstituted phenyl group, and C having an asterisk indicates an asymmetric atom,

Process for producing optically active halogen-containing alcohols using

A novel antiferroelectric liquid crystal compound is disclosed which is represented by the following formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently selected from C.sub.3 -C.sub.18 alkyl groups, respectively, Rf is a lower fluoroalkyl group, X is a group selected from the group consisting of --O--, --COO--, --OCO--, and --CO--, or a single bond, (A) and (B) each is a group independently selected from the group consisting of phenyl, biphenyl, and naphthalene group which may be substituted with a halogen atom, and C having an asterisk indicates an asynunetric carbon atom. A process for producing the antiferroelectric liquid crystal compound is also disclosed.
