Deuterium Isotope Effect in the Reaction of An throne Oxidation with Molecular Oxygen Catalyzed with Aliphatic Amines

摘要

Deuterium isotope effect in the process of the amine-catalyzed anthrone oxidation with molecular oxygen was studied. Reaction proceeds by oxygen insertion in C-H bonds in the position 10. Isotope effect is observed only at the stage of the anthranolate anions reaction with oxygen, and not at the stage of their formation. Therefore it is a secondary isotope effect.
