Abstract

Process for preparing organosulphinyl- and organo-sulfonyl-carboxylic acid organo-derivatives, and especially a compound of formula ** (See formula) ** where R is a member of the group consisting of hydrogen, levyalkyl, halolevialkyl, cycloalkyl, cycloalkylalkyl, ** (See formula) ** wherein X1 is a member of the group consisting of hydrogen, halogen, levyalkyl, trifluoromethyl, levialkoxy, carboxyl, levyalkylsulfonyl and ** (See formula) ** where X1 is as defined, R1 is a member selected from the group consisting of hydrogen, halogen, trifluoromethyl, levyalkyl, levialkoxy, and when linked to adjacent carbon atoms of the benzene ring, two X radicals can be combined to form a bond 1,3-butadienilºnico; Z is a member of the group composed of -SO-R2 and -SO2R2, where R2 is selected from the group consisting of levialquilo, levialcoxialquilo, 2-amino-2-carboxy-levialquilo, halolevialquilo, alkoxycarbonyl-levialquilo, carboxilevialkyl, cycloalkyl, cycloalkylalkyl, ** (See formula) ** wherein X2 is a member selected from the group consisting of hydrogen, halogen, levyalkyl, trifluoromethyl, levialkoxy, carboxyl, levyalkylsulfonyl, ** (See formula) ** where X2 is as defined; ** (See formula) ** and -CnH2n-Z, where Z is as already said; m, in each case, is an integer of value 1-4-, and n, in each case, is an integer of value 1-5; which comprises the reaction of a compound of formula ** (See formula) ** where R, R1, R2, X, m and n are as defined above, with an oxidant; and the acid addition salts of the preceding compound, prepared by usual means.
