    Abstract: The invention relates to a method for producing o-chloromethyl benzoic acid chlorides of formula (I), in which R to R can be the same or different and represent hydrogen C1-C4 alkyl, halogen or trifluoromethyl, by reacting benzo-condensed lactones of formula (II), in which R to R have the above-mentioned meaning, with thionyl chloride. The inventive method is characterized in that the reaction is carried out in the presence of catalytic quantities of a boric acid, boric acid anhydride, borate, boronic acid or boronic acid ester and in the presence of catalytic quantities of a quaternary ammonia salt.
