Abstract
Regioselective bromination of alkylated bi-and ter-thiophenes affords key building blocks for the synthesis of higher, isomerically pure alkyl oligothiophenes. For all new compounds, unequivocal structural assignment is based on a detailed analysis of the fully coupled 13C, 1H NMR spectra.Keywords
