摘要：

Thermolysis of [Pt(PPh3)(2)(C2H4)], [Pt(PPh3)(3)] or of various complexes of the type [Pt(PPh3)(2)(alkyne)] in toluene gave the dinuclear platinum(I) complex [(Ph3P)Pt{mu-C6H4(PPh2)-2} (mu-PPh2)Pt(PPh3)] in ca. 60% yield as a consequence of both C-H and P-Ph cleavage of co-ordinated triphenylphosphine. The complex, which has been identified by mass spectrometry, NMR (P-31, Pt-195) spectroscopy and single-crystal X-ray diffraction analysis, is probably identical with some of the compounds formulated in the literature either as [Pt-2(PPh3)(4)] or [Pt-2(mu-PPh2)(2){C6H4(PPh2)-2}(2)]. The other product of the reaction is the known trinuclear compound [Pt-3(mu-PPh2)(3) (Ph)(PPh3)(2)].
