Abstract: IT HAS BEEN DISCOVERED THAT ARYLPHOSPHINE HALIDES CAN BE PRODUCED BY REACTING AN ARYL HALIDE WITH WHITE PHOSPHORUS AT ELEVATED TEMPERATURES IN THE PRESENCE OF A LEWIS ACID CATALYST. TO ILLUSTRATE, CHLOROBENZENE IS REACTED WITH WHITE PHOSPHORUS AT 340* TO 350* C. IN THE PRESENCE OF ALUMINUM CHLORIDE CATALYST TO PRODUCE A MIXTURE OF PHENYLPHOSPHINE DICHLORIDE AND DIPHENYLPHOSPHINE CHLORIDE.
