Title:

PROCESS FOR HYDRODEHALOGENATION OF AROMATIC POLYHALIDES WITH ISOPROPYL ALCOHOL AS THE HYDROGEN SOURCE

Document Type and Number:

WIPO Patent Application WO/2003/074455

Kind Code:

A1

Abstract:

A process for hydrodehalogenation of aromatic polyhalides, characterized by conducting hydrodehalogenation of an aromatic polyhalide in a reaction system comprising an organic solvent, an aromatic polyhalide, an aqueous solution of an inorganic base as the scavenger for the hydrogen halide to be formed by hydro- dehalogenation of the aromatic polyhalide, isopropyl alcohol as the hydrogen source for the hydrodechlorination, and a catalyst system composed of both an organonickel complex catalyzing the hydrodehalogenation of the aromatic polyhalide and PPh₃.
