In one aspect, the disclosure relates to a method for functionalizing hydrocarbons. In a further aspect, the method involves heating a hydrocarbon with a composition having an acid and an oxidant. In other aspects, the composition can further include an iodine-based compound and/or a compound having formula A.sub.aX.sub.n. In any of these aspects, the oxidant can be regenerated in situ or in a separate regeneration step. Also disclosed are functionalized hydrocarbons produced by the disclosed method. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
