Type II Photoreaction of 2-Benzoylcycloalkanones: Conformational Control in the Biradical Formation and in the Behavior of Biradicals

Abstract
The photoreactivities of 2-benzoylcycloalkanones were shown to be controlled by their ring conformation; 2-benzoylcycloalkanones underwent the Type II elimination and/or cyclization, and/or the α-cleavage reaction.
