(Mes=2,4,6-trimethylphenyl; SEt2=diethyl sulfide) as a major product. When mesityllithium reagent containing lithium bromide was used, trans-[PtBr(Mes)(SEt2)2] was obtained. Acceleration of cis–trans isomerization in the presence of mesityllithium was observed.
顺式-[PtCl2(
SEt2)2]与苯-醚混合物中略微过量的
甲基锂反应得到反式-[PtCl(Mes)(
SEt2)2](Mes=2,4,6-三甲基苯基;
SEt2=
二乙基硫醚) 作为主要产品。当使用含有
溴化锂的
甲基锂试剂时,得到反式-[PtBr(Mes)(
SEt2)2]。观察到在均苯
锂存在下顺反异构化加速。
