ABSTRACT:
Process for the dehalogenation of aryl and alpha-araliphatic halides comprising contacting the aryl halide or alpha-araliphatic halide with hypophosphite salt, in the presence of a catalytic amount of a noble metal catalyst. This process is useful in the field of organic synthesis and for the removal of environmentally hazardous aryl and alpha-araliphatic halides, including polychlorinated biphenyls and dibenzo-p-dioxins.
