An oxidative coupling reaction of fluoroalkylamines with arylboronicacids has been achieved for the first time. Fluorine has profound influence on the reactivity and fluoroalkylated amines have the following reactivity trend: difluoroethylamine > trifluoroethylamine > pentafluoropropylamine ≈ heptafluorobutylamine.

A straightforward N‐trifluoroethylation of anilines has been developed based on silver‐catalyzedNH insertions with 2,2,2‐trifluorodiazoethane (CF3CHN2). Mechanistically, the reaction is proposed to involve migratory insertion of a silver carbene as the key step. In contrast, when amides are employed as the substrates under similar reaction conditions, O‐trifluoroethylation occurs to afford trifluoroethyl

Exogenous photocatalyst-free, single nickel-catalyzed carbon–heteroatomcoupling under visible-light irradiation is reported. Over 15 classes of nucleophile can efficiently couple with aryl/alkene halides to afford valuable heteroatomic arenes/alkenes. The unprecedentedly broad substrate scope and late-stage modification of valuable molecules fully demonstrate the benefits of the method.
