Not surprisingly, therefore, numerous methods have been described for their synthesis.(5, 6) The classical Paal–Knorr reaction is still the most frequently used.(7) Substituted thiophenes can also be obtained from a naked thiophene ring by functionalization through α-metalation or β-halogenation.(5) In view of the special importance of thiophenes, new routes are nevertheless still needed. We envisaged, therefore, to exploit the broad applicability of the radical ...
