Solfato di idrogeno di tetrabutilammonio

Descrizione:

Solfato di idrogeno di tetrabutilammonio (TBAS) è un composto organico con la formula chimica C16H37NO4S. È un sale di ammonio quaternario, caratterizzato dal suo catione tetrabutilammonio e dall'anione idrogeno solfato. TBAS è tipicamente un solido bianco a bianco sporco che è solubile in solventi polari come acqua e alcoli, rendendolo utile in varie applicazioni, incluso come catalizzatore di trasferimento di fase nella sintesi organica. Il composto presenta proprietà tipiche dei sali di ammonio quaternario, come alta stabilità termica e la capacità di facilitare il trasferimento di ioni tra fasi. TBAS è spesso impiegato nella sintesi di composti organici, in particolare in reazioni che coinvolgono nucleofili ed elettrofili. Inoltre, può fungere da tensioattivo grazie alla sua natura anfifilica, che gli consente di interagire con sostanze sia idrofili che idrofobiche. I dati di sicurezza indicano che, sebbene il TBAS sia generalmente considerato a bassa tossicità, è necessario osservare misure adeguate di manipolazione e sicurezza per evitare possibili irritazioni o effetti avversi.

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
