Simple but effective and eco-friendly metal-free alkyl(aryl) transfer-aromatization-alkylation domino (ATAAD) approach was demonstrated to synthesize branched hydroquinones in good to excellent yields. This high atom economy approach proceeded through molecular iodine-catalyzed aromatization of p-quinols followed by C-C bond formation with diaryl carbinols. The use of inexpensive catalyst and easily accessible starting materials rendered this clean method more exciting for wide substrate scope to afford symmetrical and unsymmetrical branched hydroquinones. Short reaction time, easy workup and gram-scale preparation are the significant features of this hitherto unknown synthesis of the title compounds.
