An optically active manganese complex of the formula I or I': (see fig. I) (see fig. II) wherein R1 , R2 , R3 , and R4 independently represent hydrogen atom, C1 -C4 alkyl group, phenyl group which may be substituted by a halogen atom, C1-C4 alkyl group, C1- C4 alkoxyl group, cyano group or nitro group; and any two of R1 , R2 , R3 and R4 together form the C4-C8 ring, X- represents a counter anion which may form a salt, Y represents hydrogen atom, halogen atom, C1 -C4 alkyl group, C1-C4 alkoxyl group, nitro group or cyano group, R represents hydrogen atom, C1 -C4 alkyl group, phenyl group which may be substituted by halogen atom, C1-C4 alkyl group or C1-C4 alkoxyl group, or substituted silyl group and a process for producing epoxy compounds using the complex as a catalyst.
