摘要:
利用N,N-二异丙基碳二亚胺(D IC)结构中的氨基与腐植酸结构中的羧基反应,制得腐植酸缩合产物.缩合反应提高了腐植酸的稳定性能,作为催化剂的载体有利于保持催化剂的活性.然后,通过简便的方法制得了缩合腐植酸负载钯催化剂,研究了该催化剂对芳基卤与乙烯基化合物的Heck反应的催化性能.通过对温度、时间、催化剂用量、溶剂等条件对催化剂催化活性影响的研究,找出该催化剂对芳基卤与乙烯基化合物Heck反应的适宜条件,并用于催化不同取代基芳基卤与乙烯基化合物的Heck反应.结果表明:该催化剂在较温和的条件下对Heck反应也有很高的催化活性.
Abstract:
Modified humic acid was synthesized from the condensing reaction between amino groups of N,N-diisopropylcarbodiimide(DIC)with carboxyl group of humic acid.The condensing reaction can improve the stability of humic acid thereby enhance the catalytic performance of humic acid supporting Pd catalyst,with which the catalyst was prepared readily by humic acid as support and PdCl2 as Pd resource.Moreover,catalytic properties of the catalyst for Heck reaction of aryl halide with vinyl compounds were studied.Additionally,the effects of temperature,time,catalyst dosage and solvent on catalytic reaction of Heck reaction were investigated,and the activity of catalyst with the different substituted aryl halide and acrylic acid in this reaction was also studied.It was showed that the catalyst had higher catalysis activity.
