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.

For the stepwise mechanism, the ethylene molecule was firstly adsorbed at the Brnsted acid site via π-hydrogen bonding to form a stable complex, which then went through the protonation, leading to the formation of the ethoxide intermediate. Furthermore, the ethoxide reacted with the second ethylene molecule to form the butoxide product.

对于分步反应机理，乙烯分子首先通过π-氢键作用在酸性位形成稳定的吸附络合物，再进一步发生质子化并生成乙醇盐中间体，随后乙醇盐与第二个乙烯分子发生碳－碳键结合形成丁醇盐产物。

The uniform nano-sized titanic oxide mesoporous thin film which can be coated repeatedly was prepared by adding tetrahydrofuran which acts as dispersant to micro-emulsion system consisting of water,cyclohexane,hexadecyl trimethyl ammonium bromide and butyl alcohol.
