Efficient deoxygenation methodologies catalyzed by oxo-molybdenum and oxo-rhenium complexes

• Oxo-molybdenum and oxo-rhenium complexes as good catalysts for deoxygenation reactions.
• Methods for reduction of sulfoxides, nitro compounds, epoxides, N-oxides and alcohols.
• Oxo-rhenium complexes as excellent catalysts for deoxygenation of biomass resources.

The deoxygenation of organic compounds is a fundamental process in both chemistry and biology and the development of new efficient methodologies for the synthesis of deoxygenated compounds is highly desired. Among the variety of catalysts used in the deoxygenation of organic compounds, high-valent oxo-molybdenum and oxo-rhenium complexes have attracted considerable interest. This review highlights the development of efficient methods for the deoxygenation of different classes of organic compounds such as sulfoxides, aromatic nitro compounds, N-oxides, epoxides, alcohols and polyols catalyzed by oxo-molybdenum and oxo-rhenium complexes.
