Li, Zhong-Yuan Wang, Guan-Wu Palladium-Catalyzed Decarboxylative <i>Ortho</i>-Ethoxycarbonylation of <i>O</i>‑Methyl Ketoximes and 2‑Arylpyridines with Potassium Oxalate Monoester A novel method for introducing an ester group via palladium-catalyzed ligand-directed C–H activation has been explored. The <i>ortho</i>-ethoxycarbonylation of <i>O</i>-methyl ketoximes proceeded smoothly with the nontoxic and easily handled reagent potassium oxalate monoester, affording the desired products in moderate to good yields. Furthermore, pyridine could also be employed as a directing group to obtain similar results in this transformation.
