electrochemical intermolecular [3 + 2] heteroannulation of anilines with electron-deficient pyridines enabled by dual C–H radicalaminations for producing functionally diverse benzo[4,5]imidazo[1,2-a]pyridines is described. The site-selectivity of aminations of aryl C(sp2)–H bonds relies on the electronic effect of two reaction partners: each contributed two reactive sites (a C(sp2)–H bond and a nitrogen
