Abstract
The process according to the invention is a process for the electrosynthesis of teritary arylalkylphosphines by electrochemical reduction of arylhalophosphines in the presence of aliphatic halides, in an organic solvent medium. The anode, made of a reducing metal such as zinc, aluminum or magnesium, is sacrificed during the electrosynthesis. The cell is preferably non-compartmented. The process is simple and inexpensive. Teritary arylalkylphosphines are compounds which are widely used in homogeneous catalytic systems.
