Labile Alkoxyamines: Past, Present, and Future

6 May, 2014 - 20:54
Chem. Commun., 2014, Accepted Manuscript
DOI: 10.1039/C4CC01364F, Feature ArticleSylvain R.A. Marque, Paul Bremond, Gerard Audran
Alkoxyamines - per-alkylated derivatives of hydroxylamine R1R2NO-R3 - can undergo C-ON bond homolysis to release a persistent nitroxyl radical R1R2NO[round bullet, filled] and a transient alkyl radical R3[round bullet, filled]. Although they were considered...
