Abstract:

Using three readily-prepared free-radicals of DPPH type, with different oxidation potential, it is possible to generate, via one electron transfer or hydrogen-atom abstraction, short-lived radicals, characterised by the EPR spintrapping technique. PBN, DMPO and DEPMPO were employed as spin-traps. The results show that DPPH and its congeners can be successfully employed for generation of short-lived oxygen-, sulfur-, carbon-, nitrogen-, and phosphorus-centered radicals.
