Procedure

A complex according to the invention is synthesized as follows. At first, lanthanum isopropoxide is used as a metal isopropoxide and triphenyl arsinoxide is used as triphenyl oxide. Lanthanum isopropoxide, optically active binaphtol (BINOL derivative) and triphenyl arsinoxide are mixed at a ratio of 1:1:1 mol % in an argon atmosphere at room temperature for 30 minutes to 1 hour to obtain La-BINOL derivative-Ph3As═O complex.
