Abstract
Procedure for the preparation of carboxylic acids by oxidation to prepare a compound of formula: **(See formula)** where R is chosen from the group consisting of hydrogen, levialkyl, halolevialkyl, cycloalkyl, cycloalkylalkyl, **(See formula)** wherein X1 is a member of the group consisting of hydrogen, halogen, levialkyl, trifluoromethyl, levialkoxy, and carboxyl; R1 is a member chosen from the group consisting of hydrogen and levialkyl; X is chosen from hydrogen, halogen, levialkyl, trifluoromethyl, and levialkoxy, and when linked to adjacent carbon atoms of the benzene ring, two X radicals can combine to form a 1,3-butadienylene bond; m is in each case an integer of value 1-4, and n is in each case an integer of value 1-5; which comprises the reaction of a compound of formula: **(See formula)** where R, R1, X, m and n are as defined, and Z is selected from vinyl and ethynyl, carbinol, formyl, dialkoxymethyl, levyalkylcarbonyl and 1,2-dihydroxyethyl groups, with an oxidant.
