叔丁基二异丙基膦 - Introduction
Tert-butyldiisopropylphosphine (also known as TBDIP) is an organophosphorus compound with the chemical formula C11H25P.
Properties: Tert-butyl diisopropyl phosphine is a colorless liquid with a special smell at room temperature. It is soluble in organic solvents such as ethanol, acetone and methylene chloride, and insoluble in water. This compound has a relatively low boiling point and flash point, but decomposes easily at high temperatures.
Purpose: Tert-butyl diisopropyl phosphine is commonly used as a ligand for catalysts, which plays a role in improving the reaction rate and selectivity in organic synthesis reactions. It usually forms complexes with transition metals and participates in catalytic hydrogenation, oxidation, reduction and asymmetric synthesis reactions.
preparation method: the preparation of tert-butyl diisopropyl phosphine is generally prepared by reacting acetylacetonate phosphonate with tert-butyl lithium to generate an intermediate lithium salt, and then reacting with tert-butyl magnesium bromide to obtain the target product. The preparation process requires attention to the operating conditions and the molar ratio between the reactants to ensure high yield and purity.
Safety information: Tert-butyldiisopropylphosphine needs to be protected from fire and light during use and storage, and maintain good ventilation. It should avoid contact with harmful substances such as oxidants, acids and high temperatures. Wear protective gloves, goggles and laboratory suits during operation. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
