摘要：

The binuclear double-bridged acetylide complexes [pt(mu-C=CR)(C6F5)(PPh3)]2 [R = Ph (1), Bu(t) (2), SiMe3 (3)] have been synthesized from [trans-Pt(C=CR)2(Ph3)2]and [cis-Pt(C6F5)2(THF)2] (THF = tetrahydrofuran). The crystal structure of [Pt(mu-C=CPh) (C6F5)(PPh3)]2 (1) has been established by X-ray diffraction methods. The structure shows that two identical [(PPh3)(C6F5)PtC=CPh] units are joined together through eta2-bonding of M-C=CPh units. This indicates that the complex is formed via a rearrangement of groups between the two metal centres. Treatment of [Pt(mu-C=CR)(C6F5)(PPh3)]2 with L (L = PPh3, py = pyridine) produces simple bridge-cleavage reactions giving the mononuclear complexes [trans-Pt(C6F5)(C=CR)(PPh3)L] (4-9).
