Abstract Reaction between 3,3′-dibromothiophene and sodium methylate/methanol in the presence of KI/CuO afforded 3-bromo-4-methoxythiophene as a major product. It was transformed into 4,4′-dimethoxy-3,3′-bithiophene by using Pd(OAc)2 as a catalyst and agarose as a ligand. The conditions of the reaction were mild with an acceptable yield of 20 %. The product was characterized by MS, 1H NMR, and its spectra of UV-Vis and cyclic voltammetry were given. Graphical Abstract: 4,4′-dimethoxy-3,3′-bithiophene was synthesized from 3-bromo-4-methyloxy thiophene in the homogeneous system formed by water and agarose.[Figure not available: see fulltext.]
