A nickel-catalyzed intramolecular Grignard-type addition of aryl bromides to C=O was developed. By using Ni(dppe)Br2 as a catalyst and zinc powder as a reducing agent, the reactions of 2-((2-bromophenyl)amino)-1-arylethanones proceeded smoothly in 1,2-dimethoxyethane solvent to afford 3-hydroxyindolines as intermediates, which underwent dehydration reaction to furnish a range of indole derivatives in moderate to excellent yields (up to 90%).

Key words: nickel, addition reaction, aryl bromide, dehydration reaction, indole
