Descrição geral

Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. It is composed of hydrogen and fluoride. Hydrofluoric acid is a colorless and highly corrosive liquid. It is commonly used in the manufacture of hydrocarbons and polishing and conditioning glass. Additionally, it is used as a catalyst and in the synthesis of fluoride-containing compounds, and semiconductors.

Aplicação

Hydrofluoric acid solution can be used as a reagent to synthesize:
  • Cyanohydrin alkyl ethers via chiral Bronsted acid-mediated hydrocyanation of vinyl ethers with silyl cyanides.
  • N, N-Dimethylaniline hydrochloride salts via Pd-catalyzed Buchwald-Hartwig amination of aryl triflates with dimethylamines.
It can also be used as a catalyst for the amidation of carboxylic acids with amines to synthesize amides.
