摘要

The direct electroreduction of aromatic acyl bromides gave aromatic 1,2-diketones.The best result was obtained using a Pb cathode in acetonitrile containing Bu_4NClO_4 as a supporting electrolyte.Aromatic acyl bromides substituted by an electron-donating group afforded 1,2-diketones in moderate-to-good yields,whereas acylated endiols were formed exclusively from aromatic acyl bromides substituted by an electron-withdrawing group.
