以壳聚糖为载体,负载金属Pd作为催化剂,研究了其对酰氯和三丁基锡化合物偶联反应的催化活性,详细考察了影响反应的各种因素,得出反应的最佳条件:有机锡试剂与酰氯的用量都是10mmol,催化剂用量0.2g,溶剂丙酮用量20ml,反应时间20h。催化剂可以重复使用,催化剂循环使用5次,偶联反应的产率仍为50%。 Using chitosan as the carrier and metal Pd as the catalyst, the catalytic activity of the coupling reaction on the acid chloride and tributyltin compounds was investigated. The factors affecting the reaction were investigated in detail. The optimal reaction conditions were as follows: organotin reagent With the amount of acid chloride are 10mmol, the amount of catalyst 0.2g, the amount of solvent acetone 20ml, the reaction time 20h. The catalyst can be reused, the catalyst is recycled 5 times, and the yield of the coupling reaction is still 50%.
