C-H, Si-H and C-F abstraction with an extremely electron poor I(III) reagent.

The recently discovered I(III) reagent NO 2 -C 6 H 4 -I(OTf) 2 is found to rapidly react with hydride sources, including HSiEt 3 and relatively hydridic C-H precursors. These represent the first distinct reactions involving direct hydride abstraction by I(III) under ambient conditions. Direct C-F abstraction is also demonstrated, as well as oxidation of cyclic alkenes to aromatic rings, all representing new reactions for I(III) demonstrating the very high reactivity of NO 2 -C 6 H 4 -I(OTf) 2 .
