We have developed an efficient Pd‐catalyzed directed C—H bromination protocol, in which dimethyl sulfoxide (DMSO) is employed as oxidant with hydrobromic acid aqueous solution (HBr(aq)) as bromide source. The DMSO/HBr(aq) system, which is novelly and efficiently utilized in transition‐metal catalyzed C—H activation, illustrates its practicability by the operational simplicity, inexpensive and readily
我们已经开发了一种有效的Pd催化的定向C-H溴化方案,其中使用二甲基亚砜(DMSO)作为氧化剂,氢溴酸水溶液(HBr (aq))作为溴化物源。DMSO / HBr (aq)系统在过渡金属催化的CH活化中得到了新颖而有效的利用,其操作简便,价格低廉且易于获得的起始原料以及高溴原子经济性说明了其实用性。
