Treatment of a range of platinum(II) halide (mainly chloride) complexes with diazomethane has been examined. Formation of both mono- and bis-halogenomethyl products has been observed. With one exception, methylene insertion appears to occur only when the metal–halogen bond is trans to a group of high trans influence (olefin, phosphine, isocyanide, alkyl, or hydride). With the trans-chlorohydrido derivatives
已经研究了用重氮甲烷处理一定范围的卤化铂(Ⅱ)(主要是氯化物)配合物的方法。已经观察到单卤代和双卤代甲基产物的形成。除了一个例外,亚甲基插入似乎仅在金属-卤素键被反式转变为具有高反式影响力的基团(烯烃,膦,异氰化物,烷基或氢化物)时发生。与反式-chlorohydrido衍生物研究,最初形成的反式- (氯甲基)氢基产品重新排列为反式- (氯)甲基物种。讨论了亚甲基插入和重排过程的机理。
