  α-alkylated ketones has been disclosed via the reaction of primary alcohols with secondary alcohols and ketones by using [IrCl(COD)(NHC)] complexes as a catalyst. Various α-alkylated ketones were obtained in high yields from the alkylation of alcohol with alcohol and ketone with alcohol through a borrowing hydrogen reaction by using 0.05–0.5 mol % iridium(I) and a catalytic amount of KOH (5–10 mol %)

  通过使用[IrCl（COD）（NHC）]络合物作为催化剂，通过伯醇与仲醇和酮的反应，已经公开了形成α-烷基化酮的高效且绿色的方法。通过使用0.05–0.5 mol％的铱（I）和催化量的KOH（5–10 mol％）通过借位氢反应，通过醇与醇的烷基化和酮与醇的酮的高收率获得各种α-烷基化的酮。在空气中并在很短的反应时间内作为碱。
