Binuclear platinum(II)–dppm acetylides and the formation of fluxional complexes of the type [Pt(η1-dppm)2(C
CR)2](dppm = Ph2PCH2PPh2)
Abstract
High-yield syntheses of two new types of dppm (PH2PCH2PPh2) complexes are described: (i) the fluxional complexes trans-[Pt(CCR)2(η1-dppm)2], and (ii) the ‘face-to-face’ binuclear complexes [Pt2(C
CR)4(η2-dppm)2](R = Ph or p-tolyl).
