Abstract: A practical, catalytic entry to α,α,α‑trisubstituted (α‑tertiary) primary amines by C–H functionalisation has long been recognised as a critical gap in the synthetic toolbox. We report a simple and scalable solution to this problem that does not require any in situ protection of the amino group and proceeds with 100% atom‐economy. 

Abstract: Visible light catalysis allows the regioselective synthesis of oxazolines in high yields. The mild photosensitized manifold leverages the intermolecular formation of oxazolines with a wide functional group tolerance on both benzoyl azides and alkenes partners. Mechanistic investigations suggest the sensitization of the azide moiety as the key activation step.

Abstract: Tri(9-anthryl)borane was successfully applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CF₃I. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with C₃F₇I and C₄F₉I. Mechanistic studies revealed that the photoredox catalysis involves an oxidative quenching pathway.
