Triethylamine trihydrofluoride Chemical Properties,Usage,Production

Application

The t-butyldimethylsilyl (TBDMS) group is the most widely used 2'-OH protection in synthesis of oligoribonucleotides. The TBDMS-group became much used particularly after it was combined with phosphoroamidite methodology and was also the choice when H-phosphonate based RNA-synthesis was introduced. Removal of TBDMS-protection is most commonly done with 1 M tetrabutylammonium fluoride (TBAF) in tetrahydrofuran (THF). These conditions has proven efficient.

Chemical Properties

clear yellow liquid

Uses

Triethylamine trihydrofluoride acts as a mild and selective fluorinating agent used in the synthesis of acid fluorides and alkyl fluorides. It is also used in the synthesis of vicinal difluorides from epoxides, 3-fluoroazetidine. It is utilized as a selective reagent for the cleavage of O-silyl groups in carbohydrates, nucleotides and cyanohydrins. It is actively involved in the electrochemical fluorodeiodination of alkyl iodides and fluorodesilylation in beta-lactams.

Uses

Mild and selective reagent that has been used in the fluorination of a wide variety of compounds. For a review, see Aldrichimica Acta.

General Description

Triethylamine trihydrofluoride (TREAT-HF) is a mild and selective reagent for the fluorination of a wide variety of compounds.
