Abstract

Two kinds of the phosphorus-centered radicals produced from hydrogen atom abstraction by 2i2-diphenyl-l-picrylhydrazyl(DPPH) were trapped by Af-/ert-butyl-a-phenylnitrone(PBN) and 5,5-dimethyl-l-pyrroline N-oxide (DMPO), and investigated by means of EPR spectroscopy. The spin adducts with a characteristic hyperfine coupling constant(hfcc) caused by a phosphorus atom were observed. Based on the hfcc values caused by the phosphorus and hydrogen atoms the conformational positions of the adducts trapped by PEN and DMPO are discussed.
