Abstract

Iron–tetraamido macrocyclic ligand (TAML) activators have been designed and developed to provide small-molecule mimics, the peroxidase enzymes. Fe–TAML activators are proving to be highly active catalysts that function effectively at very low concentrations from nanomolar to low micromolar. Notably, they are capable of performing many thousands of turnovers per minute under ambient conditions, of functioning over a broad pH range from acidic and most notably for iron catalyst to basic and even to highly basic, of presenting a broad range of selectivities and oxidative aggression determined by the conditions of use and the choice of catalyst over the 14 catalysts presented. The catalysts have fulfilled the design criteria and now provide the basis of platform technology for myriad applications. Published kinetics and mechanistic interpretations are reviewed to illustrate the success of the design protocol. Published applications are briefly described. A highly developed field of use involves the use of Fe–TAML–peroxide for the purification of water of persistent pollutants and hardy pathogens.
