顺式-和反式-二氯二(乙硫醚)合铂(Ⅱ)的合成和结构表征

摘要

Two hydrosilylation catalysts, cis - and trans - dichlorobis ( diethylsulfide ) platinum (Ⅱ) , were synthesized and characterized by MS, FT - IR, 1H and 13C NMR speetroscopy. 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).%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).
