Chemistry of Fluorinated Carbon Acids: Synthesis, Physicochemical Properties, and Catalysis

Abstract

The bis[(trifluoromethyl)sulfonyl]methyl (Tf₂CH; Tf=SO₂CF₃) group is known to be one of the strongest carbon acid functionalities. The acidity of such carbon acids in the gas phase is stronger than that of sulfuric acid. Our recent investigations have demonstrated that this type of carbon acids work as novel acid catalysts. In this paper, recent achievements in carbon acid chemistry by our research group, including synthesis, physicochemical properties, and catalysis, are summarized.
