environmentally friendly and economically favorable approach to the formation of C–N bonds is presented. The methodology is particularly interesting in that the reaction is realized under both solvent- and ligand-free conditions and involves the use of a low loading of a palladium catalyst dispersed with the reactants on a suitable solid support. The reaction proceeds rapidly under microwave irradiation. An environmentally
A convenient N-arylation of tetrahydroquinoline and tetrahydroisoquinoline is described using electron-poor, electron-neutral, or electron-rich arylhalide derivatives and palladium(II)-BINAP as a catalyst.
