Polymer-Supported Stannic Chloride Complex Catalysts Ⅲ. Copoly (Styrene-N-Vinylcarbazole) -Stannic Chloride Complex
【摘要】 合成了苯乙烯-N-乙烯基咔唑交联聚合物。此聚合物在氯仿中能同四氯化锡生成稳定的含氯量为20.8%的复合物(相当于1.47mmol SnCl2/g)。此复合物对许多有机反应如,酯化、缩醛、缩酮及醚化等有良好的催化活性。
【Abstract】 The cross-linked polymer carrier beads, styrene-N-vinylcarbazole (25.5%)-diviny-Ibenzene (2,6%) copolymer, were synthesized and combined with stannic chloride in chloroform to form a stable complex containing 20.8% Cl (equivalent to 1.47 mmol SnCl4/g of complex beads). The complex showed good catalytic activity for many organic reactions such as esterification, acetalation, ketal formatiom, and etherifica-tion. The catalyst can be reused for at least six times without losing its catalytic activity.
