Abstract
Reactions of 2,4-diaryl-1,1,1-trifluorobut-3-yn-2-ols with benzene in the presence of HUSY acidic zeolite (CBV-720) at 100°C in 1 h (glass high-pressure reactor) led to the formation of 1,3-diaryl-1-trifluoromethylindenes in 39–92% yield. A probable reaction mechanism was proposed, which involves formation of the corresponding trifluoromethyl-substituted propargyl cations.
