copper‐catalyzed intramolecular carbotrifluoromethylation of ene‐imines with Togni reagent as a trifluoromethylating reagent was realized. The reaction tolerates a range of substrates to give the corresponding 3‐trifluoroethylated 4‐amino‐chromans in moderate to good yields. A possible mechanism was proposed based on the experimental results.

Some 1,2-diarylimidoyl radicals were generated in the gas-phase by intramolecular radical translocation from ortho-imino-aryloxyl radicals, in turn generated under flashvacuumpyrolysis (FVP) conditions. The imidoyls reacted with XRortho′-substituents in the N-aryl group to give (in most cases) modest yields of cyclisation products. Depending on the nature of the bridging atom (X), the formation of
