Electrochemical bromination of alkyl aromatic compounds by two-phase electrolysis yields the corresponding α, α-dibrominated products. The reaction has been carried out in a single-compartment electrochemical cell using aqueous sodium bromide (40–50%), containing a catalytic amount of HBr as electrolyte, and chloroform, containing an alkyl aromatic compound, as the organic phase with a Pt plate as anode at 10–15°C
摘要 通过两相电解对烷基芳族化合物进行电化学溴化,生成相应的 α, α-二溴化产物。该反应是在单室电化学电池中进行的,使用溴化钠水溶液 (40-50%),含有催化量的 HBr 作为电解质,氯仿,含有烷基芳族化合物,作为有机相,带有 Pt 板在 10–15°C 时作为阳极。两相电解可产生高产率 (70–90%) 的二溴甲基、双(溴甲基)和双(二溴甲基)芳烃,具体取决于通过的电荷。
