Abstract:

Perchloric acid adsorbed onto silica gel (HClO4-SiO2) was found to be a highly efficient, inexpensive and recyclable catalyst for the selective α-bromination of carbonyl compounds using N-bromosuccinimide by stirring in n-hexane at room temperature under mild and heterogeneous conditions.
