The development of catalytic methods for the effective functionalization of methane yet remains a challenge. The best system known to date is the so-called Catalytica Process based on the use of platinum catalysts to convert methane into Me bisulfate with a TOF rate of 10-3 s. In this contribution, the authors report a series of silver complexes containing perfluorinated tris(indazolyl)borate ligands that catalyze the functionalization of methane into Et propionate upon reaction with Et diazoacetate (EDA) by using supercritical carbon dioxide (scCO2) as the reaction medium. The employment of this reaction medium has also allowed the functionalization of ethane, propane, butane and isobutane. The synthesis of the target compounds was achieved using silver-boron-indazole derivatives as catalysts, such as [hydrotris[4,5,6,7-tetrafluoro-3-(trifluoromethyl)-1H-indazolato-κN1]borato(1-)-κN2,κN2′,κN2”](2-propanone)silver, [hydrotris[4,5,6,7-tetrafluoro-3-(1,1,2,2,2-pentafluoroethyl)-1H-indazolato-κN1]borato(1-)-κN2,κN2′,κN2”](tetrahydrofuran)silver. The tilte compounds thus formed included propanoic acid Et ester, butanoic acid Et ester, 3-ethylpentanoic acid Et ester, 3-methylhexanoic acid Et ester, heptanoic acid Et ester, pentanoic acid Et ester, 3-methylbutanoic acid Et ester, 4-methylpentanoic acid Et ester, hexanoic acid Et ester, 3-methylpentanoic acid Et ester.
