摘要
本文首次采用纤维素氧膦 -钯络合物为催化剂 ,以丙酮为溶剂 ,有机锡试剂与二元酰氯偶联合成二元酮化物。该反应具有催化活性高、选择性强、反应条件温和、催化剂可以重复使用、在空气中稳定等特点 ,是由易得二元酸合成二元酮的新方法。
A new mathod is studied for the synthesis of diketones with the crosscoupling reaction of organotin reagents and diacyl chlorides catalyzed by cellulose oxyphosphine palladium complex compound. With this method, the catalyst has high catalytic activity and chemical selectivity and can be reutilized. The reaction has higher yields、milder conditions and simpler workup.
