A simple, scalable, and sustainable access to salicylamides from O-aryl carbamates was achieved using lithiumamides as easy-to-handle metalating agents under bench-type aerobic conditions. Tunable regioselective ortho- and lateral metalations in eco-friendly cyclopentyl methyl ether (CPME) allow fast anionic migrations under air, with an unexpected beneficial contribution from biorenewable protic

Well-defined ruthenium carboxylate complexes enabled unprecedented ruthenium-catalyzed C(sp(2))-H hydroxylations on benzamides with PhI(OAc)(2) as the oxidant at a remarkably low catalyst loading of 1.0 mol %.
