Disclosed are: a process for producing an optically active epoxy compound and an optically active sulfoxide compound; a ligand and a complex for use in the process; and a process for producing the complex. Specifically disclosed are: an optically active titanium-salen complex, an optically active titanium-salalen complex and an optically active titanium-salan complex having structures represented by formulae (21a), (21b), (22) and others; a process for producing an optically active epoxy compound or an optically active sulfoxide compound through the asymmetric oxidation reaction of an olefin compound or a sulfide compound using any one of the above-mentioned complexes as a catalyst; a ligand and a complex for use in the process; and a process for producing any one of the above-mentioned complexes. |
