93.8% conversion into acetic acid with 100% selectivity was achieved in the calcium‐catalyzed carboxylation of methane [Eq. (a)]. In the catalyst system, CaCl 2 is eventually converted into CaO . , which abstracts an H atom from methane. The resulting CH 3 . radical is trapped by CO, and CH 3 CO . is converted with trifluoroacetic acid into acetic acid via the mixed anhydride. TFA=trifluoroacetic acid, TFAA=trifluoroacetic anhydride.
