The herein presented EPR spectroscopic study of the same system witnesses the formation of S = 1/2 reactive iron species. Its EPR parameters, in combination with its reactivity pattern toward cyclohexene and with independently obtained VT-MS data, allow for its reasonable assignment to the reactive [((Me2)PyTACN)Fe-V=O(OH)](2+) (4c) species" , "dc.description.sponsorship": "The authors thank the Russian Foundation for Basic Research, grants 12-03-31709 and 12-03-00782, for financial support.
