Efficient alpha-Alkylation of Arylacetonitriles with Secondary Alcohols Catalyzed by a Phosphine-Free Air-Stable Iridium(III) Complex
A well-defined and readily available air-stable dimeric iridium(III) complex catalyzed alpha-alkylation of arylacetonitriles using secondary alcohols with the liberation of water as the only byproduct is reported. The alpha-alkylations were efficiently performed at 120 degrees C under solvent-free conditions with very low (0.1-0.01 mol %) catalyst loading. Various secondary alcohols including cyclic and acyclic alcohols and a wide variety of arylacetonitriles bearing different functional groups were converted into the corresponding alpha-alkylated products in good yields. Mechanistic study revealed that the reaction proceeds via alcohol activation by metal-ligand cooperation with the formation of reactive iridium-hydride species.
