Abstract

A practical synthetic method for the synthesis of aryl bromide was developed through regioselective bromination of boronic acid (BA) in the presence of poly N-bromosulfonamide-melamine (PBBSM). In this regard, a novel heterogeneous support, cross-linked poly sulfonamide-melamine (PEMA-PSA), has been successfully synthesized to stabilize bromine with high surface functional group density (6.6 mmol Br+/g). The prepared reagent is a novel brominating reagent that combines the effective functions of N-bromosulfonamide, N-bromosulfonamide-melamine and melamine groups. The structure of PBBSM was characterized using XRD, FT-IR, HNMR, TGA, FESEM, EDX, and TGA analysis.
