Electron transfer catalysis is an effective method for the acceleration of Diels-Alder reactions between two substrates of similar electron density. The dependence of the selectivity of the Diels-Alder reaction between (R)-alpha-phellandrene and 4-methoxystyrene catalyzed by photoinduced electron transfer with tris(4-methoxyphenyl)

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.
