Abstract

One-pot synthesis of 2-aryl benzothiazoles from gem-dibromomethylarenes using 2- aminoarylthiols is described. Benzothiazoles were obtained in high chemical yields under mild conditions. This transformation would facilitate synthesis by short reaction times, large- scale synthesis, easy and quick isolation of the products, which are the main advantages of this procedure.
