Abstract
Pd/C was found to catalyze the Suzuki-Miyaura coupling reaction of halophenols in aqueous media. When halophenols were treated with ArB(OH)(2) and a catalytic amount of 10% Pd/C (0.3 mol % Pd) in aqueous K(2)CO(3) solution, the corresponding hydroxybiaryls were obtained in a high yield or quantitatively. The palladium catalyst was easily recovered and reused.
摘要
发现钯碳（Pd/C）可催化卤代酚在水介质中的铃木-宫浦（Suzuki-Miyaura）偶联反应。当卤代酚在碳酸钾（K₂CO₃）水溶液中与芳基硼酸（ArB(OH)₂）及催化量的10%钯碳（0.3 mol%钯）反应时，可高产率或定量得到相应的羟基联芳基化合物。钯催化剂易于回收并重复使用。
