It was found that the samples PVP-PdCl2-CdCl2 and PVP-PdCl2-HgCl2, compared with PVP-PdCl2, exhibited much higher catalytic activity and dechlorination selectivity, and the yields of the coupling by-products were obviously decreased. For example, when p-chloroaniline was used as substrate, the reaction time was shortened to 1/8, and the yield of dechlorination product was about 25 times as much as the original one, and when p-chlorotoluene was used as substrate, the yield of coupling by-product catalyzed by bimetallic catalyst was 1/390 of that catalyzed by monometallic catalyst.

与负载型单金属催化剂PVP-PdCl2相比， PVP-PdCl2-CdCl2和PVP-PdCl2-HgCl2对氯代芳烃脱氯有高得多的催化活性和脱氯选择性，且偶联副产物显著减少；以对氯苯胺为底物时，双金属催化下的反应时间缩短为单金属催化下的1/8，而脱氯产物收率提高25倍；底物为对氯甲苯时，双金属催化下的偶联副产物仅为单金属催化下的1/390。
