Transition Metal Catalysts Bearing Multidentate Ligands for Efficient and Environmental Benign Oxidations by H 2 O 2

In this perspective, two different classes of multidentate ligands (aminotriphenolate and dipyridinimine) and the corresponding metal (Ti, V, Mo, W, Fe) complexes are described. These catalysts can activate efficiently the environmental benign H 2 O 2 oxidant, promoting a wide variety of oxidative processes (sulfoxidations, N ‐oxidations, epoxidations, haloperoxidation, alcohol oxidation, hydroxylation).
