2,5-Diarylthiophene-1-oxides have been prepared from readily available arylacetylene precursors via zirconacyclopentadiene intermediates. The isolated yields of the desired thiophene-1-oxides are comparable to those obtained from the oxidation of thiophene derivatives while avoiding the formation of over-oxidation products. Furthermore, this route offers broader versatility than commonly used methods
