✦ Synopsis

The catalytic hydrodechlorination of chlorobenzene with NirC, PdrC and Ni Pd rC in ethanol was studied with 2 D 98 2

13 Ä 1 4 Ž . and C H NMR. Two dechlorination routes of this reaction ionic and free-radical are suggested depending upon the nature of the active hydrogen species. At the same time two competitive sources of hydrogen for hydrogenolysis of the `Ž . C Cl bond -molecular hydrogen and solvent ethanol molecules -are readily apparent from experiments with molecular deuterium.
