The nucleophilic addition of sodium acetylide to 1,3-diketonates derived from 1-aryl-4,4,4-trifluorobutane-1,3-diones is reported. Tertiary 1,4-alkynediols containing CF3 and aroylmethyl groups are synthesized. 5,5′-Diaryl-3,3′-bis(trifluoromethyl)-2,2′-bifurans are prepared via a novel double cyclization of these alkynediols. |
