Application

When employed with TEMPO, this acridinium photocatalyst promotes the site-selective amination of a variety of simple and complex aromatics with heteroaromatic azoles. When ammonium carbamate is used as the amine, anilines can be achieved directly.
9-Mesityl-3,6-di-tert-butyl-10-phenylacridinium tetrafluoroborate is an acridium-based photocatalyst that can be an alternative to transition-metal-based photocatalysts due to its higher chemical stability and attenuated redox potential.

The Nicewicz lab is focused on the discovery of new and powerful reaction methodologies that proceed via the intermediacy of highly reactive cation radical species. Included in these transformations are anti-Markovnikov selective additions of amines, alcohols, carboxylic acids, amides and mineral acids to alkenes.
