The Redox Chemistry of Mono-and Bis (acyl) phosphane Oxides
European Journal of Organic Chemistry, 2014(2):331–337.
Mono- and bis(acyl)phosphane oxides are usually utilized as photoinitiators for radical polymerizations. This manuscript reveals the electrochemically reversible reductions of these molecules, leading to the corresponding radical anions. The radical anions, which have been characterized by EPR and ENDOR spectroscopy, display remarkable delocalization and ion-pairing behavior that can be rationalized by theoretical calculations.
