Syntheses of cis- and trans-Bis(X-phenyl)bis(tributylphosphane)platinum(II) Compounds with Substituents of π-Acceptor Character in the Platinum-Bound Phenyl RingsA new synthetic route to the title compounds via cis-bis(4-bromophenyl)bis(tributylphos-phane)platinum(II) (cis-2a) and cis-bis(4-lithiophenyl)bis(tributylphosphane)platinum(II) (cis-3) is described. By this method the compounds cis-{Pt[P(nBu)3]2[C6H4X-(4)]2} (X = D, Si(CH3)3, CO2H, CO2CH3, CN, COC6H5) (cis-2b-g) and trans-{Pt[P(nBu)3]2[C6H4I-(4)]2} (trans-2h) have been synthesized; cis-2a-c, e-g have been transformed into their trans- isomers trans-2a-c, e-g by catalysis with tetrabutylammonium iodide.
Notes:
Ein neues Verfahren zur Synthese der Titel-Verbindungen über cis-Bis(4-bromphenyl)-bis(tributylphosphan)platin(II) (cis-2a) und cis-Bis(4-lithiophenyl)bis(tributylphosphan)-platin(II) (cis-3) wird beschrieben. Mit dieser Methode wurden die Verbindungen cis-{Pt[P(n-Bu)3]2[C6H4X- (4)]2} (X = D, Si(CH3)3, CO2H, CO2CH3, CN, COC6H5) (cis-2b-g) und trans-{Pt[P(n-Bu)3]2[C6H4I- (4)]2} (trans-2h) synthetisiert; aus cis-2a-c, e-g wurden unter Katalyse mit Tetrabutylammoniumiodid die zugehörigen trans-Isomeren trans-2a-c, e-g erhalten.
