Alkynul Compounds of Transition Metals, XXIX. Alkynyl[ethylenebis(diphenylphosphine)] complexes of Platinum(II)cis-[PtCl2(dpe)] reacts with alkali acetylides in liquid ammonia or liquid methylamine to yield nonionic monomers of the type cis-[Pt(C≡C̊)2(dpe)] (dpe = (C6H5)2P[CH2]2P(C6H5)2; R = H, CH3, C6H5). The analogous reaction with the divalent anion of o-diethynylbenzene, however, gives the polymeric cis-[Pt(C≡C)2C6H4(dpe)]n, cis-[Pt(C≡C)2C6H4(dpe)]n. With an excess of acetylide polymeric complexes of the type [K2Pt(C≡C̊)4(dpe)]n are precipitated.
Notes:
Durch Umsetzung von cis-[PtCl2(dpe)] mit Alkaliacetyliden in flüssigem Ammoniak bzw.flüssigem Methylamin werden nichtionische, einkernige Verbindungen des Typs cis-[Pt(C≡C̊)2(dpe)] (dpe = (C6H5)2P[CH2]2P(C6H5)2; R = H, CH3, C6H5) dargestellt. Eine analoge Reaktion mit dem zweiwertigen Anion des o-Diäthinylbenzols hingegen führt zu einem koordinationspolymeren cis-[Pt(C≡C)2C6H4(dpe)]n. Die Anwendung eines Acetylidüberschusses führt zu polymeren Komplexen des Typs [K2Pt(C≡C̊)4(dpe)]n.
