Abstract
An easy synthesis of aryl phosphonates by oxidation from aryldichlorop hosphines with iodine in good yields is described. Aryldichlorophosphi nes are obtained by reaction of phosphorous trichloride with some arom atics in presence of various Lewis acids. BiCl3 and Bi(OTf)(3) are use d for the first time and bismuth trichloride is, for the first time in the case of anisole or thioanisole phosphonylation, used as a true re generable Lewis acid catalyst in a reaction of direct phosphonylation of aromatics.
