    Description / Table of Contents: The Reductive Elimination of the Biphenyl System from Substituted trans-Diphenylbis(triphenyl-phosphane)platinum(II) Compoundstrans-Diarylbis(triphenylphosphane)platinum(II) (aryl = C6H5, 3—CH3C6H4, 4—CH3C6H4, 3—CH3OC6H4, 4—CH3OC6H4, 3—(H3C)2NC6H4) (trans-1a-f) have been synthesized. The trans-configuration in this type of compounds is demonstrated by an X-ray analysis of the parent compound trans-[Pt(PPh3)2(C6H5)2]. The thermolysis of trans-1a-f yields  -  despite the trans-position of the phenyl rings  -  stereospecific reductive elimination of the biphenyl system in a concerted reaction.
    Notes: Die Verbindungen trans-Diarylbis(triphenylphosphan)platin(II) (Aryl = C6H5, 3—CH3C6H4, 4—CH3C6H4, 3—CH3OC6H4, 4—CH3OC6H4, 3—(H3C)2NC6H4) (trans-1a-f) wurden synthetisiert. Die trans-Konfiguration dieses Verbindungstyps wurde zusätzlich durch eine Röntgenstruktur-analyse der Stammverbindung trans-[Pt(PPh3)2(C6H5)2] belegt. Bei der Thermolyse von trans- 1a-f wurde  -  trotz der trans-Stellung der Phenyl-Ringe  -  in einer konzertierten Reaktion stereospezifisch das Biphenyl-System eliminiert. Der Mechanisms dieser reduktiven Eliminierung wird diskutiert.
