Spin trapping, and electron transfer

Electron transfer, in thermal and photochemical activation of electron donor-acceptor complexes in organic and organometallic reactions, 29,185 Electron-transfer, single, and nucleophilic substitution, 26,1 Electron-transfer, spin trapping and, 31,91 Electron-transfer paradigm for organic reactivity, 35, 193... 

Extended studies later showed that the radical cation mechanism of equations (6) and (7) is prevalent in strongly oxidizing systems (Eberson, 1992 Eberson and Nilsson, 1993), especially under photolytic conditions where excited states are formed (Eberson, 1994). The latter normally can act as strong oxidants or reductants, as in equation (11), and thus can create radical ions under seemingly mild conditions. Since this type of mechanism was judged to be much more common than thought, the name inverted spin trapping was coined for it in view of the inverted situation of electron demand which appears when an electron is formally transferred between the spin trap and the nucleophile or electrophile see equations (13)-(16).
