Abstract

Brominated benzenes and other bromoaromatic compounds react with hypochlorites in biphasic systems leading to the formation of chloroaromatics. The presence of the phase-transfer catalyst, tetra-n-butylammonium bisulfate, contributes to the rate of bromobenzene conversion to chlorobenzene. The replacement process involves chlorine atom intermediacy and halide molecule pi-complexes. In addition, the reactions that contain phase-transfer catalysts exhibit slight oxygen and light sensitivity.
