palladium-catalyzed methylation of C–H bonds of benzoic acids with di-tert-butyl peroxide as the methylating reagent under an external oxidant and ligand-free conditions has been achieved. The reaction is found to be directed by a weakly coordinating carboxyl group, offering a facile route for the synthesis of highly functionalized ortho-methyl benzoic acids.
在外部氧化剂和无配体条件下,已经实现了钯催化的过氧化二叔丁基作为甲基化试剂的苯甲酸C–H键的甲基化反应。发现该反应由弱配位的羧基引导,为合成高度官能化的邻甲基苯甲酸提供了简便的途径。
