Abstract
A versatile synthetic route involving the use of organotin compounds has been applied for the preparation of functionalized oligothiophenes. Substituted bithiophenes have been synthesized via the coupling reaction of 2-bromothiophenes with 3-trimethylstannylthiophene. The latter reagent couples with bromoaromatics, bromoheteroaromatics and 2,5-dibromothiophenes to give the corresponding 3-arylthiophenes, 3-heteroarylthiophenes and terthiophenes, respectively. 2-Trimethylstannylthiophene couples with 2,5-dibromo-3-arylthi ophenes to give 3-aryl-α-terthiophenes. The structures of the new compounds were confirmed by elemental analysis, mass spectrometry, 1H- and 13C-NMR spectral data.
