(Matrix presented) The reaction of CH4 with CO2 has been performed in anhydrous acids using VO(acac)2 and K 2S2O8 as promoters. NMR analysis establishes that the primary product is a mixed anhydride of acetic acid and the acid solvent. In sulfuric acid, the overall reaction is CH4 + CO 2 + SO3 → CH3C(O)-O-SO3H. Hydrolysis of the mixed anhydride produces acetic acid and the solvent acid. When trifluoroacetic acid is the solvent, acetic acid is primarily formed via the reaction CH4 + CF3COOH → CH3COOH + CHF3.

A mild and efficient synthetic method has been developed for the esterification of O-alkyl alkylphosphonic-and carboxylic-acids using polymer-supported sulfonated magnetic resins. Polymer-supported resins are recovered using an external magnet and reused several times.
