We present here an efficient and ligand-free cross-coupling reaction of organic diselenides with aryl boronic acids using a catalytic amount of CuO nanoparticles in DMSO at 100 °C under air atmosphere. This is a general cross-coupling reaction and was performed with organic diselenides and aryl boronic acids bearing electron-withdrawing and electron-donating groups affording the corresponding selenides
我们在此介绍了在空气中100°C的DMSO中使用催化量的CuO纳米颗粒在有机二硒化物与芳基硼酸之间进行有效且无配体的交叉偶联反应的方法。这是一般的交叉偶联反应,是用带有负载吸电子基团和供电子基团的有机二硒化物和芳基硼酸进行的,从而以良好或极好的收率提供了相应的硒化物。可以容易地回收CuO纳米颗粒并将其用于进一步的催化反应。
