[reaction: see text] A novel thiourea-based C2-symmetric ligand was synthesized, and its application in the palladium-catalyzed Heck and Suzuki coupling reactions of arenediazonium salts was evaluated. The reactions, which were performed at room temperature, without added base, and under aerobic conditions, produced product in 4 h with good yield. The corresponding arenediazonium salts were easily
[反应:参见正文]合成了一种新型的基于硫脲的C2对称配体,并评价了其在钯催化的ned烯氮鎓盐的Heck和Suzuki偶联反应中的应用。在室温下,不添加碱的情况下,在好氧条件下进行的反应在4小时内以良好的收率产生了产物。一步即可轻松地从苯胺生成相应的烯二唑鎓盐。
