ABSTRACT:A simple, efficient and rapid method has been developed for high-yielding regioselective nuclear monobromination of arom. and heteroarom. compds. using NBS in the presence of sulfonic-acid-functionalized silica at room temp. The catalyst worked under heterogeneous conditions and could be recycled.
