The authors studied the effect of chlorides of a few scores of nontransition and transition elements on the catalytic activity of choloroplatinic acid in the hydrosilylation of unsaturated compounds, as also on the regioselectivity of this process. Aluminum, germanium, cerium, neodymium, niobium, and tantalum chlorides enhance the catalytic activity of H/sub 2/PtCl/sub 6/ substantially in phenylacetylene hydrosilylation by triethylsilane and appreciably increase the yield of the adduct formed obeying the free-radical addition rule. Mercury, tin, phosphorus, antimony, bismuth, and sulfur chlorides inhibit hydrosilylation almost completely. Acetylene can be hydrosilylated by R/sub 3-n/SiHCl/sub n/ at usual pressure and temperature (20-50/sup 0/C) by using the catalytic system H/sub 2/PtCl/sub 6/-AlCl/sub 3/ (1:200-1:500)
