The cross-coupling reaction of sodium tetra-arylborates with acyl chlorides to give high yields of unsymmetric ketones has been carried out at 20°C in the presence of Pd(OAc)2 and Na2CO3 in dry or aqueous acetone. Under aqueous conditions arylboronic acids react smoothly with benzoyl chloride resulting in substituted benzophenones.
四芳基硼酸钠与酰氯的交叉偶联反应产生高产率的不对称酮,已在干燥或含水丙酮中,在Pd(OAc)2和Na 2 CO 3存在下于20°C进行。在水性条件下,芳基硼酸与苯甲酰氯平稳反应,生成取代的二苯甲酮。

Aromatic ketones were synthesized via a palladiumcatalyzedcross-couplingreaction of boronic acids with acylchlorides in the presence of Na2CO3 at room temperature under solvent-free conditions. The ligand-free and mild reaction conditions, highly rapid reaction rate and good to excellent yields are important features of this method.
在室温,无溶剂条件下,在Na 2 CO 3存在下,硼酸与酰氯的钯催化交叉偶联反应合成了芳香酮。无配体和温和的反应条件,快速的反应速率以及良好至极好的收率是该方法的重要特征。
