Catalytic and switchable C‐H functionalization of N‐heteroarenes under easily tunable conditions is a robust but challenging tool for construction of biologically relevant compounds. Recently, a general electrochemical strategy has been developed for direct C‐H carboxylation of N‐heteroarenes with CO2, and by simply choosing different types of cell setups, carboxylated products are furnished with excellent and tunable site selectivity. This study also paves the way for regul...
