Syntheses and Thermal Behaviour of Substituted cis-Bis(aryl)bis(triphenylphosphane)platinum(II) CompoundsThe compounds cis-[Pt(PPh3)2(3-XC6H4)2] (X = H, CH3, OCH3, N(CH3)2) (3a-d) and cis-[Pt(PPh3)2(3-XC6H4)(3-YC6H4)] (X = H, CH3, CH3, OCH3; Y = CH3, OCH3, N(CH3)2) (5a-f) have been synthesized; they eliminate at temperatures beneath 150°C in a stereospecific reaction the biphenyl system. The differential-calorimetrically measured elimination temperatures and the constitutions of the formed substituted biphenyls are discussed with respect to the reaction path.
Notes:
Die Verbindungen cis-[Pt(PPh3)2(3-XC6H4)2] (X = H, CH3, OCH3, N(CH3)2) (3a-d) und cis-[Pt(PPh3)2(3-XC6H4)(3-YC6H4)] (X = H, CH3, OCH3; Y = CH3, OCH3, N(CH3)2) (5a-f) wurden synthetisiert; bei Temperaturen unterhalb 150°C wird aus ihnen in einer reduktiven Eliminierung stereospezifisch das Biphenyl-System gebildet. Aus den differential-kalorimetrisch gemessenen Zersetzungstemperaturen und den Konstitutionen der gebildeten substituierten Biphenyle werden Aussagen über den Reaktionsablauf abgeleitet.
