The Si-Si bond in XSiMe2SiMe2Y (X, Y = F, F; Cl, Cl; Cl, Me; Br, Me) was readily cleaved with Pt(PEt3)3 to give cis-(XMe2Si)(YMe2Si)Pt(PEt3)2 complexes. On the other hand, ISiMe2SiMe3 selectively underwent oxidative addition at the Si–I bond to result in the formation of trans-(Me3SiMe2Si)PtI(PEt3)2.
XSiMe2SiMe2Y (X, Y = F, F; Cl, Cl; Cl, Me; Br, Me) 中的 Si-Si 键很容易被 Pt(PEt3)3 裂解,得到顺式-(XMe2Si)(YMe2Si)Pt(PEt3 )2 复合体。另一方面,ISiMe2SiMe3 在 Si-I 键上选择性地进行氧化加成,导致形成反式-(Me3SiMe2Si)PtI(PEt3)2。
