Cross-Coupling Reaction in the System of Aryl Halide- Arylacetylene-Alkene under “Ligand-free’’ Catalityc Conditions
The results of the study of aryl halide-arylacetylene-alkene three-component coupling using the simplest “ligand-free” (without organic ligand additives) catalytic systems based on palladium salts are presented. It was found that the route for arylacetylene cross-dimerization with alkene realized in the reaction system along with the formation of the product of the three-component coupling. The possibility for controlling the reaction selectivity of the particular products formed is also shown.
