Abstract
| - We have found that unreactive and insoluble polymeric iodosobenzene [PhIO]n induced aqueous benzylic C−H oxidation to effectively give arylketones, in the presence of KBr and montmorillonite-K10 (M-K10) clay. Water-soluble and reactive species 1 having the unique I(III)−Br bond, in situ generated from [PhIO]n and KBr, was considered to be the key radical initiator during the reactions.
