to 1-(trifluoromethyl)furan derivatives is reported. 4-Aryl-1,1,1-trifluorobut-3-en-2-one was iodinated and subsequently reduced to give the corresponding alcohol. The resultant iodo compound was then subjected to coupling with phenylacetylene to furnish an (E)-3-aryl-2-(2-phenylethynyl)-1-(trifluoromethyl)allyl alcohol, which could be cyclized by means of AgOTf to furnish a 2-(trifluoromethyl)furan
