中文摘要：

合成分析了含有桥式硫原子二酚盐配体的新型有机铋配合物，并发现它们在亲核试剂（I^-）存在下对CO2和环氧丙烷环加成反应合成碳酸丙烯酯表现出很高的催化活性和选择性．

英文摘要：

Novel organobismuth complexes bearing a sulfur-bridged biphenolate ligand were synthesized and characterized. They show high catalytic activity and selectivity for the solvent-free synthesis of propylene carbonate from CO2 cycloaddition with propylene oxide in the presence of iodide nucleophilic reagents.
