The first catalytic intermolecular oxidative cross‐coupling reaction between two different carbonyl compounds was achieved by using cumenehydroperoxide as an environmentally friendly, mild oxidant in the presence of a cyclic guanidinium hydroiodide derivative as a catalyst. Cross‐coupling reaction between variouβ ketoamides and oxindoles took place smoothly, and the corresponding 1,4‐dicarbonyl compounds

obtained by adding a Brønstedacid, which was supported by the calculation result including the increase of Mayer bond order and the shortening of the I-O bond length. Moreover, the fact that the system of AIBX and TFA could oxidize various alcohols to their corresponding carbonyl compounds would indicate that AIBX constitutes a cyclic benziodoxole structure underacidicconditions. In addition, an efficient
