Professor Brian Frost

The Frost group has a longstanding interest in aqueous phase organometallic chemistry with an emphasis on water-soluble phosphine ligands. One focus of this research group has been centered on the chemistry of the neutral, air stable, and water-soluble heterocyclic phosphine 1,3,5-Triaza-7-phosphaadamantane (PTA). PTA is a small phosphine ligands with a cone angle of ~103°. PTA binds metal centers quite strongly and is electronically more donating than PPh₃. Ruthenium complexes of PTA have exhibited impressive anticancer activity. A wide variety of transition metal complexes of PTA have been utilized as catalysts for reactions such as hydrogenation, C-C bond forming reactions, atom transfer radical addition, and nitrile hydration.
