| Abstract | ||
| Two series of new heteroaldonitrones were prepared and identified . Series A was prepared by reaction of benzyl hydroxyl amine with helroaldehydes derived from ( pyrrol, thiophene , furan and pyridine ) while series B was prepared by reaction of phenyl hydroxyl amine with the same set of hetroadlehydes, then various spectroscopic studies and other analysis (l.R , U.V , NMR and elemental analysis ) were done for the prepared nitroncs to prove its validity. The spin trapping properties of these compounds have been evaluated by using ESR technique . All tested nitrones were trapped by methyl radical which was generated by ( Fe+2 /H2O) in a mixture of H2O / DMSO to form a relatively stable nitroxide radicals . | ||
