Nitroxide-mediated radical processes

In the present short review article recent achievements in nitroxide- mediated radical polymerizations are presented. The basic concept behind these reactions, which is the Persistent Radical Effect (PRE), will be briefly explained. The effect of the nitroxide structure on the polymerization process will be discussed. Moreover, results of nitroxide- mediated radical polymerizations in aqueous dispersions will be summarized. Finally, applications of the PRE to environmentally benign radical chemistry such as nitroxide-mediated alkoxyamine isomerization and carboaminoxylation reactions are presented. Moreover, the potential use of microwave-induced heating to conduct these thermal radical reactions will be discussed. (c) 2005 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.
