A practical synthetic method for the synthesis of aryl bromide was developed through regioselective bromination of boronic acid in the presence of poly-N-bromosulfonamide-melamine (PBBSM). In this regard, a novel heterogeneous support, cross-linked poly sulfonamide-melamine, 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, 1H NMR, TGA, FE-SEM, EDX, and TGA analysis.

聚-N-溴磺酰胺-三聚氰胺作为一种新型溴化试剂用于芳基硼酸的区域选择性同溴化
在聚-N-溴磺酰胺-三聚氰胺(PBBSM)存在下，通过硼酸的区域选择性溴化，开发了一种合成芳基溴的实用合成方法。在这方面，已成功合成了一种新型多相载体，即交联聚磺酰胺-三聚氰胺，以稳定具有高表面官能团密度（6.6 mmol Br + /g）的溴。所制备的试剂是一种新型溴化试剂，它结合了N-溴磺酰胺、N-溴磺酰胺-三聚氰胺和三聚氰胺基团的有效功能。使用 XRD、FT-IR、1 H NMR、TGA、FE-SEM、EDX 和 TGA 分析表征 PBBSM 的结构。
