Ethyl 3-amino-4,4,4-trifluorobutanoate - Introduction
3-Amino-4,4,4-trifluorobutyric acid ethyl ester, also known as Lai's reagent (LDA), is an organic compound. Its molecular formula is C5H10F3NO2.
nature, Lai's reagent is a colorless liquid, with a strong smell of ammonia. It is soluble in non-polar solvents such as benzene, diethyl ether and dimethylformamide. The compound is very sensitive to air, moisture and light.
The main use of Lai's reagent is as a strong alkali reagent. It can react with acid compounds to form the corresponding salts. In addition, it is also commonly used in the basic hydrolysis step of acid-catalyzed reactions in organic synthesis, and can be used to prepare acids or anhydrides.
in terms of preparation method, the common preparation method of Lai's reagent is to react butyryl fluoride (C4H7COF) and ammonium chloride (NH4Cl) under nitrogen atmosphere to generate 3-amino -4,4, 4-Trifluorobutyric acid ammonium salt (C4H8F3NO2H). This salt is then reacted with potassium carbonate (K2CO3) in the presence of potassium bicarbonate (KHCO3) to produce 3-Amino-4,4,4-trifluorobutyric acid ethyl ester.
Regarding safety information, Lai's reagent is a strong alkali, which is irritating and corrosive. Strict safety precautions are required during operation, such as wearing protective glasses, gloves and laboratory coats. Contact with the skin or inhalation of large amounts of gas can cause severe burns, so direct contact and inhalation of the substance need to be avoided. At the same time, store it in a closed container, away from fire and oxidizing agents. Care should be taken when handling the substance to avoid reaction with incompatible substances.
