In a case study, 1,2,3-trifluorobenzene was functionalized at each of the two vacant positions [producing the benzoic acids HO2CC6H2F3-2,3,4 F(I) and HO2CC6H2F3-3,4,5 (I)] and, in addn., bromine was introduced into all available positions of I and II. The required regioflexibility was achieved by applying novel organometallic recipes such as deprotonation-triggered halogen migrations and site-discriminating
在一个案例研究中,1,2,3-三氟苯在两个空位[产生苯甲酸 HO2CC6H2F3-2,3,4 F(I) 和 HO2CC6H2F3-3,4,5 (I)] 和此外,溴被引入到 I 和 II 的所有可用位置。通过应用新的有机金属配方,例如去质子化触发的卤素迁移和位点区分竞争性卤素金属置换,实现了所需的区域灵活性。[在 SciFinder (R) 上]
