The invention relates to a process for oxidizing organic phosphorus compounds of the general formula (I) n n R.sub.3-n PX.sub.n (I) n n in which R stands for an organic radical, X stands for halogen and n stands for 0, 1, 2 or 3, to obtain compounds of the general formula (II) n n R.sub.3-n P(O)X.sub.n (II) n n in which R, X and n have the meanings given above. To this end, chlorosulfonic acid is used as oxidant and the oxidation is effected in homogeneous liquid phase. |
