The reaction of HgR2 (R = 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) with Pt(PPh3)3 gives the new stable compound <(PPh3)2RPt(HgR)> containing Pt-Hg bonds.When R contains an ortho chlorine atom (R = 2,5-C6H3Cl2; 2,3,4-C6H2Cl3 and 2,3,4,5-C6HCl4) refluxing xylene solutions of these compounds gives the complexes , with simultaneous precipitation of mercury.In the other cases the initial compounds are recovered unaltered.All the compounds containing the Pt-Hg bond react readily with CF3COOH to give a new series of compounds of formula .
