New insights into N-tert-butyl-α-phenylnitrone (PBN) as a spin trap. Part 2.1 The reactivity of PBN and 5,5-dimethyl-4,5-dihydropyrrole N-oxide (DMPO) toward N-heteroaromatic bases

The reactions of N-tert-butyl-α-phenylnitrone (PBN) and 5,5-dimethyl-4,5-dihydropyrroline N-oxide (DMPO) with a series of N-heteroaromatic bases have been studied in different solvents (benzene, dichloromethane, acetonitrile) in the presence of such oxidants as PbO2, chloranil and tetrabutylammon…
