cross-coupling of C–O bonds with widely accessible organic bromides as reactants for the preparation of ortho-arylated or -alkylated aromatic aldehydes at room temperature. The use of metallic magnesium is essential for the reaction to occur, giving it an advantage over previous reactions involving Grignard reagents that have to be prepared separately from organic halides before the coupling.
我们报告了铬催化的 C-O 键与可广泛使用的有机溴化物作为反应物在室温下制备邻芳基化或烷基化芳香醛的交叉偶联。金属镁的使用对于反应的发生来说是必不可少的,这使它比以前的反应具有优势,这些反应涉及必须在偶联前与有机卤化物分开制备的格氏试剂。
