N2 - Thiophenes I [R, R1 = H, alkyl, alkoxy, or RR1 = O(CH2)nO; n = 1-5] are suitable for the prodn. of polythiophenes which can be used as org. conductors. The I polymerize in the presence of an acid with pKa ?3.75, the conjugate base of which is nonnucleophilic. Thus, I (R = R1 = H) was prepd. by reaction of 2 mol 2-thienyllithium with benzo[1,2-c:4,5-c']bis[1,2,5]thiadiazole-4,8-dione in THF at -78 Deg and polymd. by HCO2H at room temp.
