A cobalt-catalyzed C(sp)-H oxygenation reaction to furnish aldehyde was herein reported. This transformation demonstrated high chemo-selectivity, and tolerated various methylarenes bearing electron-withdrawing substituents. This reaction provided rapid access to diverse aldehydes form methylarenes. Notably, TFA/TFAA was used for the first time as a mixed solvent in cobalt-catalyzed oxygenation of benzylic methylenes.
本文报道了一种钴催化的C(sp)-H氧化反应以制备醛。该转化表现出高化学选择性，并且能耐受各种带有吸电子取代基的甲基芳烃。该反应能从甲基芳烃快速获得多种醛。值得注意的是，三氟乙酸/三氟乙酸酐首次被用作钴催化苄基亚甲基氧化反应的混合溶剂。
