Ligand-Free Catalytic Cross-Coupling in the System ArylHalide–Arylacetylene–Alkene

Three-component cross-coupling in the system aryl halide–arylacetylene–alkene in the presence of simplest ligand-free palladium catalysts gave products of both 1+1+1-coupling and cross-dimerization of arylacetylene with alkene. The possibility of controlling the reaction selectivity has been demonstrated.
