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.
