Stability of Carbocyclic Phosphinyl Radicals: Effect of Ring Size, Delocalization, and Sterics
Anna Ott, Péter R. Nagy, Zoltán Benkő
Abstract
). Therefore, it is essential to apply sterically demanding bulky substituents on the α-C-atoms. Tweaking the steric congestion enabled us to propose radicals that are expected to be stable against dimerization and, consequently, may be realistic target species for synthetic investigations. The effects contributing to the stability of radicals having sterically encumbered substituents have also been explored.
