Abstract
Catalytic systems and methods for oxidizing materials in the presence of metal catalysts (preferably manganese-containing catalysts) complexed with selected macropolycyclic rigid ligands, preferably cross-bridged macropolycyclic ligands. Included are using these metal catalysts in such processes as: synthetic organic oxidation reactions such as oxidation of organic functional groups, hydrocarbons, and heteroatoms, including enantiomeric epoxidation of alkenes, enynes, sulfides to sulfones and the like; oxidation of oxidizable compounds (e.g., stains) on surfaces such as fabrics, dishes, countertops, dentures and the like; oxidation of oxidizable compounds in solution, dye transfer inhibition in the laundering of fabrics; and further in the bleaching of pulp and paper products.
