Arenediazonium o-benzenedisulfonimides have been used as efficient electrophilic partners in Au(I) catalysed Suzuki coupling reactions. The synthetic protocol is general, easy and produced either biaryls or heteroaryl arenes in good yields (51 positive examples, average yield 80%). o-Benzenedisulfonimide was recovered at the end of the reactions and was reused to prepare the starting salts for further
Arenediazonzon邻苯二磺酰亚胺已被用作Au(I)催化的Suzuki偶联反应中的有效亲电子伙伴。合成规程是通用的,容易的并且以高收率生产联芳基或杂芳基芳烃(51个阳性实例,平均收率80%)。在反应结束时回收邻苯二甲磺酰亚胺,并重新用于制备起始盐以用于进一步的反应。机械学的见解表明,邻苯二磺酰亚胺阴离子起电子转移剂的作用,并促进了不需要光催化剂或外部氧化剂存在的催化循环。
