The hypervalent iodine-induced arene cross coupling via a single-electron-transfer (SET) oxidation process could proceed in some extent even in heteroaromatic compounds, that is, several types thiophenes 1, using alkyl benzenes 2 as coupling partners. The structure of the obtainable heteroaromatic biaryl products could be elaborated by utilizing the known metal-catalyzed coupling technology, i.e., Negishi cross coupling, for the synthesis of multiple arylated (bi)thiophenes.
