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.

Highly efficient thermal radical carboaminoxylations of various olefins by using the novel alkoxyamine A to give adducts of type B are described. It is reported that these radical addition reactions can be performed in a microflow reaction system. As compared to conventional batch reaction setup, significantly higher yields are obtained by running carboaminoxylations using the microflow system under analogous conditions.
