摘      要：Novel mono-and bimetallic scorpionate aluminum compounds have been designed and characterized by spec-troscopic methods.These organometallics complexes,in combination with tetrabutylammonium bromide as cocatalyst,displayed good catalytic activity for the cycloaddition of styrene oxide and CO_(2) under ambient con-ditions.Among the compounds tested,monometallic complex 3 featuring diethylamino groups showed the highest catalytic activity.This catalytic system catalyzed the formation of cyclic carbonate products from their corresponding epoxides at room temperature and 1 bar of CO_(2) pressure in the absence of a solvent in good yields and excellent selectivities.
