Tetrabutylammonium hydrogensulfate (TBAS) is a trifluoroacetic acid salt of tetrabutylammonium. It is soluble in water and alcohols and can be used as an acid catalyst for many organic reactions. TBAS reacts with ethylene diamine to form the sulfate ester, which undergoes nucleophilic substitution with hydrogen fluoride to produce hydrofluoric acid. The reaction mechanism of TBAS consists of two steps: the first step involves the formation of a tetrahedral intermediate between the sulfonium cation and the fluoride anion, and the second step involves the nucleophilic attack by water on this intermediate. The x-ray crystal structure of tetrabutylammonium hydrogensulfate has been determined by NMR spectroscopy. This compound is chemically stable at room temperature but decomposes at higher temperatures. The hydroxyl group in tetrabutylammonium hydrogensulfate
