摘要：
A convenient and catalyst-free method for the a-bromination of acetophenones using NaBr and CHCl3 in biphasic electrolysis with H2SO4 as a supporting electrolyte at room temperature has been introduced. This approach results in an excellent yield of a-bromo acetophenones with high selectivity in a beaker-type cell equipped with C/SS electrodes. To achieve good yield with high current efficiency, various optimization studies are carried out and reported.
