Formal [3+2] annulation of arylacetylenes and α,β-unsaturated carbonyl compounds is achieved in a one-pot reaction by successive treatment of the acetylenes with aniline and a catalytic amount of Ru3(CO) 12 and NH4PF6 and C-H bond activation catalyzed by [ReBr(CO)3(thf)]2. The result suggests that the second rhenium-catalyzed indene formation is not disturbed by the first catalyst system.
