The meta-CAr—H bond formylation of arenes has been achieved using CHBr3 as a formyl source in the presence of [Ru(p-cym)(OAc)2] as a catalyst. This method provides efficient access to the preparation of various meta-substituted aromatic compounds, such as alcohols, ethers, amines, nitriles, alkenes, halogens, carboxylic acids, and their derivatives, through transformation of the versatile formyl group
在[Ru(p- cym)(OAc)2 ]作为催化剂的存在下,使用CHBr 3作为甲酰基源已经实现了芳烃的间位-C Ar -H键甲酰化。通过转化通用的甲酰基,该方法提供了有效制备各种间位取代的芳族化合物的途径,例如醇,醚,胺,腈,烯烃,卤素,羧酸及其衍生物。此外,机理研究表明,关键的活性物种是五角形钌循环络合物。
