A rhodium-catalyzed amination reaction of aryl halides with amines has been developed with the use of a N-heterocyclic carbene (NHC) ligand (IiPr = 1,3-diisopropylimidazol-2-ylidene). The active metal species responsible for the reaction progress was identified. The developed procedure of the Rh-catalyzed N-arylation is convenient to carry out under mild reaction conditions displaying a wide range of substrate scope and high degree of functional group tolerance.
Structurally diverse arylchlorides were silylated with sodium silylsilanolate reagents in the presence of a Ni(cod)2 catalyst complexed with a phosphine ligand; PMe2Ph for electron-rich substrates, and PCy2Ph for electron-deficient ones. The mild reaction conditions allowed the silylation of various arylchlorides including functionalised drug molecules.
