The syntheses of cis-bis(phenyl)platinum(II) compounds with substituents of increasing Van der Waals volumes in the ortho-positions of the phenyl rings are reported.The existence of E,Z-atropisomers with respect to the torsion about the platinum-carbon ?-bonds in these compounds is demonstrated NMR-spectroscopically.The E,Z-diastereoisomers of bis(2-t-butoxymethyl-6-methyl-phenyl)2-1,2-bis(diphenylphosphino)ethane>platinum(II) have been separated and isolated on a preparative scale.
