OH Radical Trapping with Benzoxazine nitrones: a combined computational and spectroscopic study. [PDF]

open access: yes, 2015
none1The hydroxyl radical addition onto 3-aryl-2H-benzo[1,4]oxazin-4-oxides spin traps yielded very persistent nitroxides. Their EPR spectra showed unusually large splitting due to the trapped OH proton, whose assignment has been possible by means of the
