Abstract

The possibility for the synthesis of 5-chloro-2-hydroxybenzoic, 4-chloro-2-hydroxybenzoic, and 3-chloro-2-hydroxybenzoic acids via regioselective carboxylation of p-, m-, and o-chlorophenols, respectively, with sodium ethyl carbonate has been demonstrated. Simple and convenient procedures developed in this study for the synthesis of chlorohydroxybenzoic acids can be used for their preparative and industrial synthesis.
