"Are Radicals Absolutely Necessary?  Strategies for Promoting Nickel-Mediated Bond Formation"

on March 29, 2017 at 4:10 PM in Neville Hall, Room 003.

 

Abstract:

A challenge in base metal catalysis involves one-electron transformations that lead to undesired side-products. Organic radicals and single electron transfer pathways are often invoked in modern Ni-catalyzed reactions. I present two strategies for promoting Ni-mediated bond formation in the absence of organic radicals. Redox-active ligands stabilize Ni(I) and Ni(III) intermediates and allow for classical two-electron transformations. Furthermore, bimetallic catalysts could achieve two-electron transformations by accepting/donating one electron to/from each metal center. The development of new methods is assisted by fundamental studies of bond formation processes.
