Abstract

An alternative manufacturing process scheme was developed to synthesize monochloro- substituted aromatic compounds in high selectivity, involving oxidative chlorination by using HCl-H2O2. Thus, 2-chlorotoluene, 2-chloroaniline, and 2-chlorophenol were synthesized by oxidative chlorination followed by desulphonation or decarboxylation. Oxidative chlorination of 4-methylbenzenesulphonic acid, 4-methylbenzoic acid, 4-aminobenzoic acid, and 4- ...
