顺式-[Pt（C6 F5）2（PPh 2 H）2]、[Pt（α-烯烃）3]和PPh 3（1：1：1）之间的反应导致形成Pt（II）衍生物[（C6 F5）2 Pt（μ-PPh 2）（μ-H）Pt（PPh 2 H）（PPh 3）]（1）和[{（C6 F5）（PPh 3）Pt（μ-PPh 2）（μ-H）} 2 Pt]（2）。对于1：1：2的摩尔比，反应继续进行，形成Pt（I）衍生物[（C6 F5）（PPh 3）Pt（μ-PPh 2）Pt（PPh 3）2]（3）和Pt（II）衍生物[（C6 F5）2 Pt（μ-PPh 2）（μ-H）Pt（PPh 3）2]（4）和[（C6 F5）（PPh 3）Pt（μ-PPh 2）2 Pt（H）（PPh 3）]（5）。配合物2、3和5的结构经X-射线衍射确定。光谱（IR和NMR）数据也给出了。
The reaction between cis-[Pt(C6F5)2(PPh2H)2], [Pt(norbornene)3], and PPh3 (1:1:1) results in the formation of the Pt(II) derivatives [(C6F5)2Pt(μ-PPh2)(μ-H)Pt(PPh2H)(PPh3)] (1) and [{(C6F5)(PPh3)Pt(μ-PPh2)(μ-H)}2Pt] (2). For the molar ratio 1:1:2 the reaction proceeds with formation of the Pt(I) derivative [(C6F5)(PPh3)Pt(μ-PPh2)Pt(PPh3)2] (3) and the Pt(II) derivatives [(C6F5)2Pt(μ-PPh2)(μ-H)Pt(PPh3)2] (4) and [(C6F5)(PPh3)Pt(μ-PPh2)2Pt(H)(PPh3)] (5). The structures of complexes 2, 3, and 5 have been established by X-ray diffraction. Spectroscopic (IR and NMR) data are also given.
