Oxidation with the "H2O2-manganese(IV) complex carboxylic acid" reagent -: 1.: Oxidation of saturated hydrocarbons with peroxy acids and hydrogen peroxide

The complex [LMnIV(O)(3)(MnL)-L-IV](PF6)(2) (1), where L is 1,4,7-trimethyl-1,4,7-triazacyclononane, catalyzes a highly efficient stereoselective oxygenation of saturated hydrocarbons in the presence of H2O2. A carboxylic acid is an obligatory component of the reaction mixture, while acetonitrile or acetone can be used as solvent. The reaction occurs, forming alkyl hydroperoxide, ketone, and alcohol. Substitution at the tertiary cart,on atom proceeds more easily than that at the secondary carbon atom, whereas primary C-H bonds are rather inactive. Oxidation of alkanes and alcohols with peroxy acids catalyzed by complex 1 occurs with lower efficiency.
