PROCESS FOR PRODUCING OPTICALLY ACTIVE EPOXY COMPOUND, COMPLEX FOR USE IN THE PROCESS, AND PROCESS FOR PRODUCING THE SAME
A process for producing an optically active epoxy compound on an industrial scale, comprising carrying out asymmetric epoxidation of a prochiral unsaturated compound with an oxidizer in the presence of, as a catalyst, a monomer represented by any of the following formulae (I), (I'), (II), (II'), (III), (III'), (IV) and (IV'), or a di-mu-oxo-dimer derived therefrom. In the formulae, each of R1s independently is an alkyl or aryl
each of R2s independently is an alkyl or aryl
each of R3s independently is an alkyl or aryl, provided that two R3s may be bonded with each other to thereby form a ring
each of R4s independently is a hydrogen atom, a halogen atom, an alkyl, an alkoxy, nitro or cyano
and M is a TiY2 (Y is Cl, an alkoxide or a mu-oxo ligand).
