摘要：

Rhodium PCcarbeneP pincer complexes 1-L (L = PPh3 , PPh2 (C-6 F-5), PCy3) readily facilitate deoxygenation of amine and pyridine N-oxides. The resulting complexes exhibit eta(2)-C = O coordination of the resulting keto POP pincer ligand. These eta(2)-C = O linkages in the metalloepoxide complexes are readily reduced by isopropyl alcohol and various benzylic alcohols. Thus, efficient catalytic deoxygenation of amine and pyridine N-oxides is possible using complexes 1 L and isopropyl alcohol. This represents a pioneering example of PCcarbeneP pincer complexes being used as catalysts for catalytic deoxygenation.
