Graphite Rod

A facile and sustainable electrochemical umpolung of bromide ion protocol was developed under mild reaction conditions. Transition metal catalysts and exogenous chemical oxidants were obviated for the bromination of C–H bond. Notably, graphite rod, which is commercially available at supermarkets and is inexpensive, was employed as the electrode material. This operationally easy and environmentally friendly approach accomplished the synthesis of 3-bromoindole in excellent yield and regioselectivity.

Synthetic organic electrochemistry is currently experiencing a renaissance, the merger of electrochemistry with transition-metal-catalyzed C—H activation would provide not only an environmentally friendly approach, but also offer new opportunities that conventional transition-metal catalysis may not have achieved. In this chapter, we summarize the recent progress made in catalytic C—H activation reactions using organometallic electrochemistry, including C—C, C—O, C—N, C—halogen, and C—P bond-forming reactions.
