Studies on the catalysis by lithium perchlorate and lithium trifluoromethanesulfonate of the photo-oxidation of phenols and α-phellandrene in different solvents

Abstract

The catalytic effect of aqueous solutions of lithium perchlorate and lithium trifluoromethanesulfonate on the photochemical oxidation of various phenols has been studied. Additionally, the increase of the yield of studied reactions has been observed in weakly alkaline aqueous solutions in comparison to the neutral ones. The analogous catalytic effect of 4 M or 2 M solutions in Et₂O and CH₂Cl₂ of lithium perchlorate and lithium trifluoromethanesulfonate on the reaction of α-phellandrene with singlet oxygen has been also observed.
