Nitroxide-catalyzed transition-metal-free aerobic oxidation processes

Abstract

Advances in the field of transition-metal-free nitroxide-catalyzed aerobic oxidation processes are covered in this critical review. Along with the relevant physical properties of nitroxides, their application as oxidation catalysts by using dioxygen as a reagent or terminal oxidant will be discussed. The second part of the review focuses on the use of TEMPO-based nitroxides as catalysts for aerobic alcohol oxidation. Mechanistic studies will also be addressed (130 references).
