An ionic cobalt-PNP complex enables an efficient α-alkylation of ketones with primary alcohols. A broad range of ketone and alcohol substrates provides alkylated ketones in good yields. The method was also successfully applied to a greener synthesis of quinoline derivatives using 2-aminobenzyl alcohol as the alkylating reagent.
