- Abstract:
- Under optimized conditions, 3-substituted thiophenes (EWG = COOEt, PO(OEt)2) undergo a facile and regioselective oxidative coupling reaction at carbon atom C4. The reactions were performed with various aryl boronic acids as nucleophiles in the presence of silver oxide (2.0 equiv), cesium trifluoroacetate (tfa) (1.0 equiv), benzoquinone (BQ) (0.5 equiv), and catalytic amounts of Pd(tfa)2 (10 mol %) employing trifluoroacetic acid (TFA) as the solvent.
