Insights into the mechanisms of (1) selective epoxidations and (2) C-H oxidations mediated by aminopyridine manganese complexes have been achieved on the basis of kinetic (Hammett plot analysis, KIE measuments) and isotopic (18O) labelling studies. For the first time, the incorporation of labelled oxygen into the products of oxidation catalyzed by aminopyridine manganese complexes in the presence of H2 18O was observed. The data obtained bear evidence in favour of the key role of MnV-oxo species, the most likely catalytically active sites of both processes.
