Description / Table of Contents:
On the Mechanism of the Reductive Elimination of Substituted Biphenyls from cis-Bis(aryl)bis(triphenylphosphane)platinum(II)-CompoundsThe compounds cis-[Pt(PPh3)2(4-CH3O-C6H4)2], cis-{Pt(PPh3)2[4-(CH3)2N-C6H4]2, cis-{Pt(PPh3)2[4-(CH3)2N - C6H4](4-CH3O-C6H4)}, cis-{Pt(PPh3)2[4-(CH3)2N - C6H4](C6H5)} and cis-[Pt(PPh3)2(4-CH3O - C6H4)(C6H5)] were synthesized and the temperatures of reductive elimination of substituted biphenyls measured by differential calorimetry. Linkage between the two phenyl rings to form the biphenyl system occurs exclusively at the carbon atoms bonded directly to platinum.
Notes:
Die Verbindungen cis-[Pt(PPh3)2(4-CH3O-C6H4)2], cis-{Pt(PPh3)2[4-(CH3)2N-C6H4]2, cis-{Pt(PPh3)2[4-(CH3)2N - C6H4](4-CH3O-C6H4)}, cis-{Pt(PPh3)2[4-(CH3)2N - C6H4](C6H5)} und cis-[Pt(PPh3)2(4-CH3O - C6H4)(C6H5)] wurden synthetisiert und ihre Zersetzungs-Temperaturen der reduktiven Eliminierung substituierter Biphenyle differential-kalorimetrisch gemessen. Die Verknüpfung zum Biphenyl-System erfolgt ausschließlich zwischen den unmittelbar an das Platin gebundenen Kohlenstoff-Atomen beider Phenyl-Ringe.
