Benzoylcyclohexane on irradiation on a dry silica gel surface, undergo an oxidative cleavage to give adipic acid and subsituted benzoic acid along with the Norrish Type II product. The kinetics of racemization of benzoylcyclohexane (2-benzoylcyclohexanone) in hexane, ethanol and their mixtures has been investigated by time dependence of enantiomeric purity using enantioselective HPLCIt was used to investigate the crosslinked cyclohexyl phenyl compounds under thermal and aquathermal conditions. It was used to examine the effects of molecular changes in the benzophenone molecule on phototoxic behavior.
