attention. However, employing it as a traceless direction group has rarely been reported. We developed the ruthenium-catalyzed amidation of substituted benzoic acids with isocyanates via directed C-H functionalization followed by decarboxylation to afford the corresponding meta-substituted N-aryl benzamides, in which the carboxylate serves as a unique, removable directing group. Notably, this protocol
