The yellow complex trans-[PtCl2L2] (L = PPh2CH(SiMe3)2) has been characterised. An attempt to make a similar complex with the more sterically hindered phosphine PPh2C(SiMe3)3 resulted in the loss of a trimethylsilyl group from one phosphine ligand and activation of a CH bond in another to give the white complex H2PPh2CH(SiMe3)2}, the structure of which was established by X-ray diffraction.
黄色络合物反式-[PtCl 2 L 2 ](L = PPh 2 CH(SiMe 3)2)已被表征。尝试用位阻更强的膦PPh 2 C(SiMe 3)3制备类似的配合物,导致一个
膦配体失去三甲基甲
硅烷基,另一个
膦配体活化CH键,得到白色配合物H 2 PPh 2 CH(SiMe 3)2 },其结构通过X射线衍射确定。
