Effective Use of Regio- and Enantioselective Intramolecular Carbon−Hydrogen Insertion Reactions Catalyzed by Chiral Dirhodium(II) Carboxamidates. Allylic & benzylic oxidation of alcohols takes place on surface of the MnO2, which is insoluble in solvents used for the rxn Water competes w alcohol for sites on MnO2 and thus Epoxidation of olefins under autoxidation conditions has been known for a long time and has been ascribed to the addition of peroxyl radicals to the C C bond, followed by a unimolecular ring‐closure, eliminating RO ⋅ . Allylic and benzylic oxidation of alcohols takes place on the surface of the MnO 2, which is in-soluble in the solvents used for the reaction. The allylic seleninic acid produced in the first step undergoes a [2,3]-sigmatropic rearrangement to reinstate the double bond position.
