## Abstract The EPR spectra of several nitroxide biradicals derived from substituted bis(hydroxyβureas) have been determined. The main differences in these spectra arose dur to intramolecular interaction of the nitroxide groups. Interaction was only observed for the case where the nitroxide group w
Conditions are disclosed for the formation of either mono-or di-substituted ureas by reductive alkylation, which are :readily adaptable to large scale preparations. Dehydrating agents such as acetyl chloride or Iximethylsilyl chloride effectively
