含桥式硫原子双酚盐配体的有机铋配合物的合成及其对CO_2和环氧丙烷环加成反应催化性能的研究(英文)

Synthesis of Novel Organobismuth Complexes Bearing a Sulfur-bridged Biphenolate Ligand and Their Catalytic Application to CO_2 Cycloaddition with Propylene Epoxide

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.

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.
