Organometallic Compounds Synthesis and Characterization

The synthesis of the compounds cis- and trans-{Pt[P(C6H5)3]2(2-RO-6-CH3OC6H3)Cl} (R  CH3, C2H5, CH(CH3)2, C(CH3)3; cis-5a–d, trans-5a–d) and cis-{Pt[P(C6H5)3]2(2-RO-6-CH3OC6H3)(2-CH3C6H4)} (cis-1a–d) is reported. In cis-1b, c the existence of E,Z-conformers (atropisomers) was demonstrated by 1H NMR spectroscopy. Die Synthesen der Verbindungen cis- und trans-{Pt[P(C6H5)3]2(2-RO-6-CH3OC6H3)Cl} (R  CH3, C2H5, CH(CH3)3; cis-5a-d, trans-5a-d) und cis-{Pt[P(C6H5)3]2(2-RO-6-CH3OC6H3)(2-CH3C6H4)} (cis-1a–d) werden beschrieben. Für cis-1b, c wird 1H-NMR-spektroskopisch die Existenz von E,Z-Konformeren (Atropisomere) nachgewiesen.
