A novel direct oxidative coupling of methyl-substituted N-heteroazaarenes with alcohols has been developed to construct olefins under mild condition. The reaction is catalyzed by Fe(NO₃)₃·9H₂O/TEMPO with oxygen as terminal oxidant. A variety of E-disubstituted olefins bearing diverse functional groups could be obtained selectively in moderate to excellent yields. The reaction is environmentally friendly and ligand-free.
