Mn(III)‐Cl formed by the reaction of Mn(OAc)3 and hydrochloric acid in situ, reacted with α,β‐unsaturated ketones readily to afford α,β‐dichloroketones in good yields under mild conditions. The products are key precursors for synthesis of conjugated alkynones and other organic compounds.
由Mn(OAc)3与
盐酸原位反应形成的Mn(III)-Cl ,易于与α,β-不饱和酮反应,在温和的条件下以良好的收率得到α,β-二
氯酮。该产品是合成共轭炔酮和其他有机化合物的关键前体。
