【摘要】 研究了2种硅氢化反应催化剂顺式-和反式-二氯二(乙硫醚)合铂(Ⅱ)的合成方法,并通过红外光谱、质谱、1H和13C核磁共振对这两种配合物进行了表征,确证了其化学结构。结果表明:适量的乙硫醚得到的是反式-二氯二(乙硫醚)合铂(Ⅱ),而过量的乙硫醚得到的是顺式-二氯二(乙硫醚)合铂(Ⅱ)。更多还原

【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).更多还原
