Several oxidative reactions can be effected with MnO2 in the presence of substoichiometric quantities of DDQ. These transformations include oxidative cyclization, deprotection, and dehydrogenation reactions. The use of MnO2 as a terminal oxidant for DDQ-mediated reactions is attractive based on economical and environmental factors.

series of monodeuterated benzylic and allylic ethers were subjected to oxidative carbon–hydrogenbond cleavage to determine the impact of structural variation on intramolecular kinetic isotopeeffects in DDQ-mediated cyclization reactions. These values are compared to the corresponding intermolecular kinetic isotopeeffects that were accessed through subjecting mixtures of non-deuterated and dideuterated

through radical cation intermediates can be avoided by using constant potential conditions and current is maintained through the interplay between cation stability, oxidant strength, overpotential, and reaction concentration.
