Organometallic reactivity is heavily influenced by the environment created through ligand coordination to the metal. A series of imidazolyl substituted biaryl monophosphine ligands have been synthesized for use in transition metal catalysis. The rigid biphenyl scaffold provides a means for restricting conformation and unique placement of a pendent Lewis basic group in the secondary coordination sphere. Coordination of these ligands to form gold complexes have proven to be useful for alkyne addition reactions. Computational analysis supports the idea that transition metal complexes containing these new ligands can act bifunctionally in reactions that involve proton transfer or hydrogen bonding. Coordination chemistry and reactivity of late transition metal complexes of these new ligands will be discussed.
