摘要

在80℃的DMF/H2O介质中，在Pd(PPh3)4和Na2CO3的存在下，苯硼酸与含有离子液体载体或中性类似物的4-硅基溴苯的偶联反应在微波辐射下比传统加热下进行得更快、更有效。在微波条件下进行一般缓慢的Suzuki-Miyaura反应是一种有吸引力的方法。

Suzuki-Miyaura Reaction of 4-Silyl-bromobenzenes with Phenylboronic Acid under Thermal and Microwave Conditions

The coupling reaction of phenylboronic acid with 4-silyl-bromobenzenes incorporating an ionic liquid support or its neutral analogue at 80 °C in DMF/H2O in the presence of Pd(PPh3)4 and Na2CO3 takes place much faster and more efficiently under microwave irradiation than under traditional heating. It is an attractive method to carry out the generally slow Suzuki-Miyaura reactions under microwave conditions.
