PROCESS FOR THE PREPARATION OF WATER-SOLUBLE SULPHONATED ORGANOPHOSPHORUS COMPOUNDS AND THE CARRYING OUT OF ORGANIC REACTIONS WITH BIPHASIC CATALYSIS

摘要

The invention concerns a method for preparing water-soluble sulphonated organophosphorous compounds, in particular suitable for organic reactions carried out with a two-phase catalyst. The invention is characterised in that the water-soluble sulphonated organophosphorous compound is treated before being used as catalyst ligand to eliminate at least partially the radicals and sulphite compounds. The invention also concerns the organic reactions catalysed by a two-phase system comprising a treated sulphonated organophosphorous ligand to eliminate sulphites.
