Based on the problem of various types of catalyst and according to the features of carbonylation catalysts reactions, our team has been designed a series of new metal complexes of benimidazoles, which can be used for carbonylation catalyst of industry. Seven new benzimidazole derivatives were prepared by the o-phenylenediamine、oxalic acid、glycolic acid、monomethyl monopotassium malonate、ethyl cyanoacetate、succinic anhydride. The structures of them were confirmed by IR、Elemental analsis. The crystal structures of d and e were determined by X-ray single crystal diffraction of Germanic Bruker Smart APEX II CCD. The catalysis of them was tested by carbonylation reactions.
