N2 - We report the facile activation of aryl E-H (ArEH; E = N, O, S; Ar = Ph or C6F5) or ammonia N-H bondsviacoordination-induced bond weakening to a redox-active boron center in the complex, (1−). Substantial decreases in E-H bond dissociation free energies (BDFEs) are observed upon substrate coordination, enabling subsequent facile proton-coupled electron transfer (PCET). A drop of >50 kcal mol−1in H2N-H BDFE upon coordination was experimentally determined.
