The article deals with applying NMR and EPR spectroscopy to the study of the active sites of cat alysts in two important classes of reactions: enantioselective olefin epoxidation with hydrogen peroxide cat alyzed by iron aminopyridine complexes and olefin polymerization in the presence of titanium and vanadium post metallocene catalysts.
