Organomanganese chloride reagents are alkylated in excellent yields by n-alkyl bromides in THF, at 20°C, in the presence of 3% CuI when N-methylpyrrolidone is added as cosolvant. The reaction is very chemoselective since various functional group such as chlorides, sulfonates, alcohols, carboxylic acids, esters and even ketones are tolerated.
