Photodriven oxidations of alkanes in trifluoroacetic acid using commercial and synthesized Fe(III) sources as catalyst precursors and dioxygen (O2) as the terminal oxidant are reported. The reactions produce alkyl esters and occur at ambient temperature in the presence of air, and catalytic turnover is observed for the oxidation of methane in a pure O2 atmosphere. Under optimized conditions, approximately 17% conversion of methane to methyl trifluoroacetate at more than 50% selectivity is observed. It is demonstrated that methyl trifluoroacetate is stable under catalytic conditions, and thus overoxidized products are not formed through secondary oxidation of methyl trifluoroacetate.

IX3 (X = Cl, OCOCF3, ONO2) reacts with Cd(CF3)2 complexes or Bi(CF3)3 to yield the corresponding CF3IX2 derivatives. 19F nuclear magnetic resonance spectroscopic evidence is found for + and I(CF3)2X (X = Cl, OCOCF3) in the reactions of CF3IX2 with Cd(CF3)2 complexes.During the reaction of CF3IF2 and Hg(CF3)2 the new species I(CF3)2F and cis-- are identified by nuclear magnetic resonance spectroscopy.The reactions proceed under polar conditions and can be accelerated by the addition of a Lewis acid such as BF3, B(OCOCF3)3, or Sb(V) compounds.Difluoromethyl compounds are formed as by-products.Key words: polar trifluoromethylations, trifluoromethyl iodine(III) compounds, difluoromethyl group formation.
