Various C-centered radicals can efficiently be generated through thermal C-O-bond homolysis of alkoxyamines. This method is used to perform environmentally benign radical cyclization and intermolecular addition reactions. These alkoxyamine isomerizations and intermolecular carboaminoxylations are mediated by the persistent radicaleffect (PRE). In the paper, the effect of the variation of the alkoxyamine

Thermal radical alkoxyamine isomerizations controlled by the persistent radical effect are investigated. These processes can be accelerated upon addition of substoichiometric amounts of Lewis acids, Bronsted acids and various reducing reagents. The experimental findings are further supported by simulations.
