Notes:
The electrochemical behaviour of seven N-hydroxy-N-arylacetamides (RNOHCOCH3, R = phenyl, 4-chlorophenyl, 3,4-dichlorophenyl, 4-ethoxyphenyl, 4-biphenylyl, 2-fluorenyl and 2-phenanthryl) was investigated by cyclovoltammetry. Each compound showed two different oxidation potentials, attributed to a quasi-reversible one-electron transfer in the range between 0·55 and 0·63 V and an irreversible transfer of a second electron between 0·80 and 1·20 V. Since the one-electron oxidation of N-hydroxy-N-arylacetamides gives the corresponding nitroxides, the kinetics of the self-reaction of these radicals and the concentration dependence of the product pattern were also studied.
