17745-45-8 - Introduction
n-Propylboronic acid, also known as propyl boronic acid or benzyl boronic acid, has the following properties:
1. Physical properties: n-Propylboronic acid is a colorless liquid with a special aroma. It is soluble in water and many organic solvents, such as alcohols, ethers, etc.
2. Chemical properties: n-Propylboronic acid is a boron-containing organic compound. It acts as an acid and can react with a base to form the corresponding salt. It can also perform nucleophilic substitution reactions and participate in some organic synthesis reactions.
3. Application: n-Propylboronic acid is commonly used as catalyst and ligand in organic synthesis. It can catalyze many organic reactions, such as hydrogenation, oligomerization, isomerization and so on. In addition, it is used to prepare other organoboron compounds, such as boronates and borates.
4. Preparation method: n-Propylboronic acid can be obtained by the reaction of propyl magnesium bromide with boron trichloride. After the reaction, n-Propylboronic acid is obtained by hydrolysis.
5. Safety Information: n-Propylboronic acid under normal conditions of use, with low toxicity and corrosion. However, it is still necessary to follow the safety procedures and avoid contact with skin and eyes. Wear appropriate protective gloves, glasses and laboratory clothing during use. At the same time, it should be stored in a sealed container, avoiding contact with air and humidity. If accidentally touched or accidentally eaten, seek medical attention immediately.
