Figure 5. Proposed mechanism of radical formation during irradiation of the deca-BDE in THF.

Figure 5

I. Oxygenated tetrahydrofuranyl radical. II. Tetrahydrofuranylhydroperoxyl radical. III. Hydroperoxyl radical. IV. Tetrahydrofuranyl radical. V. Nona-BDE radical. A. DMPO/•OOH. B. DMPO/•OR. C. DMPO/•tetrahydrofuranyl. D. MNP/H•. E. MNP/tert-butyl• (DTBN). [] indicates the transition state of II. Nona-BDE* is the excited state of the compound. For nona-BDE pathway 1 is major and 2 (broken arrow) is minor for further reaction.
