All you need is air: A new protocol has been developed which can mediate the coupling of aryl and vinyl boronic acids at room temperature in high yields (see scheme, dtbpy=4,4′‐di‐tert‐butyl‐2,2′‐bipyridine). The reactions take place using simple copper(II) salts under aerobic conditions and do not require the use of expensive silver oxidants.
您所需要的只是空气:已开发出一种新的协议,可以在室温下以高收率介导芳基和乙烯基硼酸的偶联(请参阅方案,dtbpy = 4,4'-二叔丁基-2,2' -联吡啶)。反应在有氧条件下使用简单的铜(II)盐进行,不需要使用昂贵的银氧化剂。
