Abstract: Synthesis of a novel α-phosphorus containing spin-trap, DEPPEPO[5-(diethoxyphosphoryl)-5-phenylethyl-1-pyrroline] N-oxide and evaluation of its ability to spin trap the hydroxyl and the superoxide anion radicals were described in the present article. The ability for trapping an active superoxide anion radicals generated in the HX/XO system and the stability of their spin adduct of DEPPEPO were analyzed. In addition, the effects of 5-phenylethyl and 5-phenyl substituted analogues of DMPO on the stereochemistry of the corresponding spin adducts were systematically illustrated.

Key words: Spin trap, Nitrone, Electron-spin Resonance(ESR), Superoxide anion
