A new method to prepare compounds of the type trans- (R = C6H5; 2,5-C6H3Cl2; 2,3,4-, and 2,4,6-C6H2Cl3; 2,3,4,5-, 2,3,4,6- and 2,3,5,6-C6HCl4 and C6Cl5) by reaction of cis- and HgR2 in the molten state is described.The reactions of the complexes with HCl, Cl2 and I2 have been examined in order to give information about the relative ease of cleavage of the various Pt- aryl bonds.The replacement of Cl by NCS suggests an associative mechanism even for the complexes in which the polychlorophenyl ligand has chlorine atoms in both ortho positions.
