The liquid-phase hydrochlorination of 4,5,6,7,8,8,-hexachloro-3′,4,7,7′-tetrahydro-4,7-methanoindene (Chlordene) catalyzed by gallium or aluminum halides occurs in the presence of water traces in an aprotic organic solvent. Complexes H2O · M2X6, where M is metal and X is halogen, catalyze this reaction. The reaction proceeds under homogeneous conditions. Under heterogeneous catalytic conditions, the solid phase in the AlCl3-CCl4 system attains the required concentration of AlCl3 in the solution. It was shown using quantum-chemical PM3 calculations that the water molecule facilitates the transfer of proton in the form of the hydroxonium ion from an HCl molecule to olefin.
