| Abstract: | Electrochemical polymerization of heterocycles such as pyrrole1 or thiophene2 has been carried out over the past few years to obtain thin films of conducting polymers I. To prepare polythiophenes mono or disubstituted in the 3 and 4 positions by electron-donating groups, we have been looking for an easier preparation of this kind of heterocycle. |
