Abstract

Procedure for the obtaining of derivatives of phosphonic and phosphine acids and of their salts, of formula (I), in which r is lower rent; r together with the carbon to which they are united form a cyclomaccanic ring c <003>; and x is hydrogen, hydroxyl, rent or aril. It consists in the dissociation reaction of the tiazolidinic ring of a compound of formula (II) or (III), in which r and r are lower rent and the other symbols have the same meaning as in formula (I). The reaction is carried out by heating the ebullition of a suspension of the compound in water, in the presence of a halohidic acid. These compounds have pharmacological applications for the treatment of inflammatory states, degenerative articular diseases and wilson's disease.
