Abstract

Procedure for the preparation of 4,4-diarylpiperidines of the general formula **(See formula)** wherein R means a hydrogen atom or a straight or branched chain alcohol radical with 1 to 6 carbon atoms or an aralkoxy, hydroxyalkoxy, oxoalcoyl, alkoxyalkoyl, aryloxyalcoyl, aryloxoalcoyl radical with 1 to 3 carbon atoms in the alcoholic chain ; and R1 signifies a hydrogen atom or an alcohol radical with 1 to 4 carbon atoms, as well as its salts, characterized in that 4-hydroxy-4-arylpiperidines of general formulas II and III are reacted **(See formula)** in which R and R1 have the above meanings and in which the 4-hydroxyl group may be replaced by other functional groups, with benzene in the presence of Friedel-Crafts catalysts, such as anhydrous aluminum chloride or boron trifluoride.
