Abstract:
     The present invention relates to a synthesis method of catalyst (R) or (S) 4-chlorine-alpha-isopropyl benzylamine-salicyl schiff base-cuprum (II) complex, including three steps of 4-chlorine-alpha-isopropyl benzylamine synthesis and resolution, and final synthesis of catalyst. As compared with original similar catalysts, the chemical efficiency obtained by use of the said catalyst can be raised by 16-20%, and its optical absorption rate is 15-18% and is more than that of similar catalyst too. Because it uses p-chloro-isophenyl-isovaleric acid as raw material, its cost is low, and therefore it can be used in various solutions (it is inert to carbene).
