Abstract

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.
