Thiophene derivativesR 0090 Practical One-Step Synthesis of Symmetrical Liquid Crystalline Dialkyloligothio-

phenes for Molecular Electronic Applications. — Oligothiophenes of type (III) are prepared by a lithiation/bisalkylation sequence from the corresponding oligothio-phenes, e.g. (I). Use of tBuOK to enhance the reactivity of lithiated oligothiophene spe-cies towards alkyl halides is crucially important. — (LEROY, J.; LEVIN, J.; SERGEYEV, S.; GEERTS*, Y.; Chem.
