Herein, we report a radical borylation of aromatic amines through a homolytic C(sp<sup>2</sup> )-N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent (<sup>Sc</sup> Pyry-OTf) thus priming the amino group for reactivity. The combination of terpyridine and a diboron reagent triggers a radical reaction which cleaves the C(sp<sup>2</sup> )-N bond and forges a new C(sp<sup>2</sup> )-B bond. The unique non-planar structure of the pyridinium intermediate, prov ...[more]
