Visible light-assisted reactions of (phenyl)(trifluoromethylsulfonylimino)-λ3-iodane with alkenes
摘要
Visible light-assisted (λ = 465–470 nm) reactions of (phenyl)(trifluoromethylsulfonylimino)-λ3-iodane with alkenes gave products of sulfonamidation and cyclization. Solvent effect on the product composition was revealed. A comparison of the reactions of the title iodane with cyclohexene carried out in the presence of N-halosuccinimides and under blue LED-light-activation conditions (440–450 nm) revealed the differences in triflamidation reaction producing cyclic (aziridine) and linear (halo amides, halo amidines) products. Plausible reaction mechanisms were discussed.
