Hemilabile Phosphorus Enamine/Imine Ligands And Their Application In Ru-Catalyzed Aqueous Hydration Of Nitriles
The insertion of aromatic nitriles into the C-Li bond of PTA-Li gave a new series of P,N k2-enaminophosphine derivatives (PTA=C(R)NH2) of 1,3,5-triaza-7-phosphaadamantane (PTA), with a characteristic double bond on the PTA cage. Oxidation or sulfuration of the ligands resulted in a mixture of …

Synthesis and Coordination Chemistry of Water-soluble Phosphines: Application to Ru-Catalyzed Hydration of Nitriles in Aqueous and Biphasic Media
… investigates the synthesis and characterization of a series of 1,3,5-triaza-7-phosphaadamantane (PTA) derivatives and their ruthenium arene complexes as potential water-soluble catalysts for aqueous and biphasic hydration of nitrile. A series of upper-rim modified PTA derivatives were prepared by …

Catalytic Mechanism and Maturation of the Metalloenzyme Nitrile Hydratase
… hydratases are metalloenzymes that catalyze the hydration of nitriles to their corresponding amides in a specific manner at ambient pressures and temperatures at neutral pH. Traditional industrial methods require high temperature and pressure, extreme pH, and heavy metals. NHases are used as …

Aqueous Organometallic Catalysis: Nitrile Hydration Catalyzed by Ruthenium(II) 1,3,5-triaza-7-phosphaadamantane (PTA) Derived Complexes
… investigates the synthesis and characterization of ruthenium complexes containing water-soluble 1,3,5-triaza-7-phosphaadamantane (PTA) and PTA derived ligands for the application of aqueous phase nitrile hydration. A series of PTA and PTA derivatives were characterized via solid-state NMR (SSNMR) …
