Abstract: Embodiments of the invention provide a tetraamido macrocyclic ligand catalytic activator bound to a carbon containing support. When combined with an oxidant, such as a peroxy compound, the carbon supported catalytic activator is a long-lived, robust oxidizing agent useful for oxidizing oxidizable compounds, such as aromatic groups, conjugated pi systems, natural and synthetic hormones, pesticides, pathogens, and dyes.

Abstract: An improved method of synthesizing a macrocyclic tetraamido compound includes protecting the amino portion of an amino carboxylic acid to form a protected amino carboxylic acid; exposing the protected amino carboxylic acid to a first solvent, preferably a hydrocarbon solvent, such as toluene or 1,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane. The carboxylic acid portion of the protected amino carboxylic acid is then converted to an activated carboxylic acid by one of esterification or acid halide formation, to form a protected amino activated carboxylic acid derivative. The protected amino activated carboxylic acid derivative is reacted with a diamine in the presence of a second solvent, such as THF or ,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane, to form a protected diamide diamine intermediate.
