| Abstract: | The promotion effects of N-donor ligands for catalytic oxidative carbonylation of methanol were studied.It was found that the base strength of ligands,the size of conjugated systems,the rigidity of skeletons and the hydrogen bonds between the ligands had remarkable influences on the calalytic performance for the(oxidative) carbonylation.The ligands with larger conjugated systems and rigid skeletons give better catalytic(activities),and intermolecular hydrogen bonds between ligands greatly decrease promoting activities.For monodentate ligands without intermolecular hydrogen bonds,those with pK_a 7 exhibit the best promoting activity.The mechanism of steric and electronic effects for the oxidative carbonylation of methanol in homogeneous(system) was discussed in detail. |
