Abstract

The facile and clean oxidative cross-coupling reaction of pyrroles has been developed using the recyclable hypervalent iodine(III) reagents having an adamantane core. The recyclable iodine(III) reagent could be recovered from the reaction mixtures as the corresponding reduced forms, i.e., the tetraiodide 2, by a simple solid-liquid separation. By re-oxidizing the recovered 2 to the initial reagent 1a using m-chloroperbenzoic acid (mCPBA), the reagent 1a can be reused.
