Direct partial oxidation of methane, ethane, and propane to their respective trifluoroacetate esters is achieved by a homogeneous hypervalent iodine(III) complex in non‐superacidic (trifluoroacetic acid) solvent. The reaction is highly selective for ester formation (>99 %). In the case of ethane, greater than 0.5 M EtTFA can be achieved. Preliminary kinetic analysis and density functional calculations
Several N-heterocyclic carbene palladium catalyzed oxidation of nonactivated sp3 C–Hbonds in linear primary and secondary trifluoroacetic acid esters have been developed. A high selectivity for the oxidation of the omega-1 carbon atom in trifluoroacetic acid n-propyl to n-octyl esters was realized by an appropriate choice of N-heterocyclic carbene palladium complexes.

Provided are methods and materials for the functionalization of a heteroalkane or arene using an oxidizing electrophile as a stoichiometric agent or catalyst. The reaction involves the replacement of a hydrogen atom on an sp3-hybridized carbon atom of the heteroalkane or of a hydrogen atom on an sp2-hybridized carbon atom of the arene. A main group element organometallic intermediate is formed that undergoes further conversion to a functionalized heteroalkane or arene.
