ABSTRACT:
Arylacetic acids and their esters, of the formula Ar(CH.sub.2 -COOR).sub.n (where Ar=aryl, R is H or a hydrocarbon radical, and n is 1 or 2) are manufactured by carbonylation of halomethylaryl compounds Ar(CH.sub.2 C).sub.n (where X is Cl, Br or I) with carbon monoxide and a catalyst one equivalent of an alkaline earth metal) in the presence of stoichiometric amounts of an inorganic base or of an alcoholate of an alcohol ROH.
