Abstract
The present invention provides a new tetradentate bis-amido bis-alkoxo, 1,2-(bis-2,20diphenyl-2-hydroxyethanamido)benzene (H.sub.4 PHAB) and various derivatives thereof. This ligand is able to stabilize high valen metal oxo complexes by providing strong sigma donor ligands and through the use of steric bulk to prevent decomposition via formation of the .mu.-oxo dimers. Disclosed are novel metal oxo structural chemistry and oxidation reactions carried out with the novel metal oxo complexes.
