Recent Advances in Rhodium-Catalyzed Electrochemical C-H Activation.

Rhodium-catalyzed C-H activation has emerged as a powerful tool for forging C-C and C-heteroatom bonds. Nevertheless, the requirement of stoichiometric chemical oxidants for oxidative transformations significantly hampered the overall sustainability of the C-H activation transformations. The emergence of merging transition metal catalysis and electrochemistry, called metalla-electrocatalysis provides an excellent opportunity to construct organic molecules efficiently and sustainably. This review highlights the recent developments of rhodium-catalyzed electrochemical C-H activation transformations, challenges and opportunities for future developments.
