Transition-Metal Catalysis for Selective Aerobic Oxidation and Epoxidation
This community develops catalysts that use molecular oxygen or hydrogen peroxide to selectively oxidize alcohols, sulfides, and olefins, aiming to replace harsh chemical reagents with efficient, selective, and sustainable methods for producing fine chemicals.
The research focuses on designing metal complexes, particularly those involving manganese, cobalt, iron, and ruthenium, to activate oxygen for specific transformations. Key reactions include the aerobic oxidation of benzyl alcohols to aldehydes, the epoxidation of olefins, and the oxidative cleavage of alkenes. A significant portion of the work involves creating heterogeneous catalysts or supported metal centers that operate in liquid phase, often utilizing Schiff base ligands or polyoxometalate frameworks to enhance selectivity and efficiency. The goal is to achieve high conversion rates for specific functional groups without over-oxidizing the substrate, a challenge central to modern synthetic and industrial chemistry.
The community is most prominent in research involving manganese, where it accounts for 1.8% of all manganese studies, and ruthenium, representing 1.9% of that element's research. It also constitutes a notable share of cobalt (1.5%) and iron (0.5%) research, reflecting the central role of these transition metals in the catalytic mechanisms studied here.
The community comprises 19,414 papers, with the highest publication volume in the Journal of the American Chemical Society, Inorganic Chemistry, and Tetrahedron Letters. Recent work continues to explore the trapping of high-valent metal-oxo species, the development of bioinspired catalysts for C–H bond functionalization, and the application of electrochemical methods to drive selective oxidations in flow systems.
