Tetrabutylammonium hydrogen sulfate

Description:

Tetrabutylammonium hydrogen sulfate (TBAS) is an organic compound with the chemical formula C16H37NO4S. It is a quaternary ammonium salt, characterized by its tetrabutylammonium cation and hydrogen sulfate anion. TBAS is typically a white to off-white solid that is soluble in polar solvents such as water and alcohols, making it useful in various applications, including as a phase transfer catalyst in organic synthesis. The compound exhibits properties typical of quaternary ammonium salts, such as high thermal stability and the ability to facilitate the transfer of ions across phases. TBAS is often employed in the synthesis of organic compounds, particularly in reactions involving nucleophiles and electrophiles. Additionally, it can serve as a surfactant due to its amphiphilic nature, which allows it to interact with both hydrophilic and hydrophobic substances. Safety data indicates that, while TBAS is generally considered to have low toxicity, appropriate handling and safety measures should be observed to avoid potential irritation or adverse effects.

Tetrabutylammonium hydrogensulfate

CAS: 32503-27-8

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
