    Abstract: A process for photochlorinating aromatic compounds in the side chain and, in particular, a process for the selective chlorination of a 2-alkyl group of 2-alkyl benzoic acid or ester is disclosed. In this process, hydrogen chloride is added to the benzoic acid or ester prior to adding chlorine in the presence of actinic radiation at a reaction temperature below the decomposition temperature of the resulting chlorinated acid or ester. A typical aromatic compound is methyl 2-methylbenzoate and the reaction is preferably carried out at a temperature ranging from about -20°C to 20°C.
