Abstract
Two hydrosilylation catalysts,cis-and trans-dichlorobis(diethylsulfide) platinum(Ⅱ),were synthesized and characterized by MS,FT-IR,1H and 13C NMR spectroscopy.Both complexes could be prepared by the reaction of potassium tetrachloroplatinate(II) with diethyl sulfide.Appropriate amount of diethyl sulfide in the reaction yields the bright yellow trans-dichlorobis(diethylsulfide) platinum(Ⅱ),while excess amount of diethyl sulfide yields cis-dichlorobis(diethylsulfide) platinum(Ⅱ).
