Phosphine, (1,1-dimethylethyl)phenyl- - Introduction
t-Butylphenylphosphine (tert-butylphenylphosphine) is an organophosphorus compound. Its chemical formula is C10H15P and its molecular weight is 168.21g/mol. The following is a detailed description of its nature, use, preparation and safety information:
Nature:
t-Butylphenylphosphine is a colorless to pale yellow liquid, soluble in organic solvents such as ether and benzene. It has a pungent odor and can easily react with oxygen in the air.
Use:
t-Butylphenylphosphine are widely used in organic synthesis and catalytic reactions. As a ligand, it can be located on the transition metal catalyst and participate in a variety of reactions, such as cross coupling reaction, hydrogenation reaction, catalytic free radical reaction and so on. In addition, it can also be used to prepare other organophosphorus compounds.
Preparation Method:
The preparation of t-Butylphenylphosphine is generally obtained by reacting phenylphosphine with tert-butyl bromide. The specific steps are as follows:
1. adding phenyl phosphine to anhydrous carbon tetrachloride to form a nitrile manganese compound,
2. After removing the solvent, add absolute ethanol.
3. The above product is reacted with an excess of tert-butyl bromide in anhydrous ether to form t-Butylphenylphosphine.
Safety Information:
t-Butylphenylphosphine has a stimulating effect on the skin and eyes, should pay attention to protection when using. It is also toxic, so avoid direct contact, inhalation or ingestion during operation. The relevant safety instructions and operating procedures should be carefully read and followed before use.
