Cis- and trans-[PtL2Cl2] (where L = aniline, 2,5-dimethylaniline and p-toluidine) have been synthesized. The cis-compounds can be isolated isomerically pure from the reaction of K[PtLCl3] and L in a mixture of water and ethanol. The trans-isomers are obtained from the isomerization of the cis-compounds. The isomers can be identified from their infrared spectra. The isomer pair, [Pt(2,5-dimethyl-aniline)2Cl2] respond to Kurnakov's test in acetone solution at room temperature. Trans-[Pt(2,5-dimethylaniline)2(thiourea)2] Cl2 has been characterized.
PLATINUM(II) AND PALLADIUM(II) COMPLEXES OF THIACYCLOOCT-4-ENES; AN UNUSUAL METAL-CATALYZED OLEFIN ISOMERIZATION

Reactions of MCl42- (M=Pd, Pt) with cis-thiacyclooct-4-ene, cis-2-methyl-thiacyclooct-4-ene and cis-2-phenylthiacyclooct-4-ene (cis-S-4-oct) give chelate complexes of general formula MCl2(cis-S-4-oct).X-ray structure determination indicates that coordination to the metal occurs through both the olefinic double bond and the sulfur atom.Reaction of CN- with the adduct obtained from PtCl42- and a mixture of cis- and trans-2-methylthiacyclooct-4-ene liberates the cis ligand, and GLC analysis excludes the presence of free trans olefin.It is suggested that platinum complexes induce extensive transcis olefin isomerization.
