Buchwald–Hartwig amination reactions was demonstrated with tunable π-acceptor bicyclic bridgehead phosphoramidite (briphos) ligands. The catalytic activity of NHC-Pd-L (L = phosphorus ligand) precatalysts depends on the electronic properties of L. A NHC-Pd-L catalyst with an N-cyclohexyl-substituted briphos ligand was found to be highly efficient. A series of C–N bond coupling reactions between primary or

The present invention discloses new organic compounds (e.g., ligands), their metal complexes and compositions using those compounds. The invention also relates to the field of catalysis. In particular, this invention relates to new compounds which when combined with suitable metals or metal precursor compounds provide useful catalysts for various bond-forming reactions, including Suzuki cross-coupling or aryl amination reactions. The invention also relates to performing Suzuki cross coupling reactions with unreactive aryl-chlorides.
