To provide a derivative of an optically active alcohol useful as a medicine or an agrochemical and an intermediate of the same.

This method of preparation for derivative of an optically active alcohol treats a derivative of an alcohol with a gas including oxygen in the presence of an optically active ruthenium complex expressed by formula (2) and light. [R1, R2, R3 and R4 are each independently a 1-8C alkyl group or phenyl group, any two of the R1, R2, R3 and R4 may joint to form a 4-8C ring, R is H, a 1-8C alkyl group, phenyl group or a 1-4C alkoxy group or the like, X1 and X2 are each independently a halogen atom, hydroxyl, NO group or the like, Y is H, a halogen atom, a 1-4C alkyl group or the like, and the binaphthyl group may be a lacemic modification or an optically active group].
