    Description / Table of Contents: Synthese and Spectroscopic Investigations of Substituted cis- and trans-Dichlorobis-(triphenylphosphane)platinum(II) CompoundsCompounds of the type cis- and trans-dichlorobis(triphenylphosphane)platinum(II) (3) with substituents of different electronic character in the phenyl rings bonded to phosphorus have been synthesized. The coupling constants 1J[195Pt,31P] and the chloro-platinum valence vibrational frequencies are demonstrated to be criteria for unambiguous discrimination between cis- and trans-configurations at platinum; a linear correlation exists between the sum of the ρ-constants of the substituents at the triphenylphosphane and the coupling constants 1J[195Pt,31P].
    Notes: Verbindungen des Typs cis- und trans-Dichlorobis(triphenylphosphan)platin(II) (3), deren an den Phosphor gebunden Phenyl-Ringe in verschiedenen Positionen mit Substitutenten unterschiedlichen elektronischen Charakters substituiert sind, werden dargestellt. Mit den Kopplungskonstanten 1J[195Pt, 31P] und den Platin-Chlor-;Valenzschwingungsfrequenzen werden Kriterien für die sichere Unterscheidung zwischen cis- und trans-Konfiguration am Platin aufgezeigt; es besteht ein linearer Zusammenhang zwischen der Summe der Substituenten-Konstanten der in das Triphenylphosphan eingeführten Substituenten und den Kopplungskonstanten 1J[195Pt, 31P].
