摘要
制备了腐植酸负载Pd/Ni双金属催化剂,该催化剂能够成功催化溴苯与丙烯酸、苯乙烯等乙烯基化合物的Heck反应,产率均在85%以上;催化剂能够不同程度地重复使用,在催化溴苯与丙烯酸反应中,催化剂重复使用3次后仍可得到42.9%的产率,而在催化溴苯与苯乙烯反应中,催化剂重复使用7次后也可得到26.7%的产率;并且对不同取代基芳基卤与丙烯酸的反应也有很好的催化活性.
The humic acid supported Pd/Ni bimetallic catalyst has been readily prepared, which can catalyze the Heck reaction of bromobenzene with acrylic acid or styrene in the yield above 85%. The catalyst can be reused to a certain extent. In the Heck reaction of bromobenzene with acrylic acid, the yield was 42.9% after the catalyst was reused for 3 times. While the yield was 26.7% after the catalyst was reused for 7 times in the Heck reaction of bromobenzene with styrene. And the catalyst can also catalyze the Heck reaction of substituted phenyl halide with acrylic acid or styrene.
