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。
