2,4-Dimethylphenylboronic - Introduction
2,4-Dimethylbenzeneboronic acid is a chemical substance whose chemical formula is C8H11BO2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 2,4-Dimethylbenzeneboronic acid is a colorless crystal or a white solid.
-Solubility: Slightly soluble in water, soluble in organic solvents.
-Melting point and boiling point: the melting point is 147-152 degrees Celsius, and the boiling point is 345 degrees Celsius.
Use:
- 2,4-Dimethylbenzeneboronic acid is often used as an important reagent in organic synthesis, especially in coupling reactions (such as Suzuki-Miyaura coupling reactions).
-It can be used to synthesize chemicals such as fluorescent dyes, drugs and polymers.
Preparation Method:
- 2,4-Dimethylbenzeneboronic acid can be obtained by hydroboration of toluene.
-This reaction usually uses methyl trifluoroboric acid (Methyltrifluoroborate) as a hydroboration reagent, and reacts with toluene under heating to obtain 2,4-Dimethylbenzeneboronic acid.
Safety Information:
- 2,4-Dimethylbenzeneboronic acid is generally regarded as a relatively safe chemical substance under normal use conditions, but the following safety information still needs to be paid attention:
-Contact with skin and eyes may cause irritation and direct contact should be avoided.
-in use should pay attention to protective measures, such as wearing gloves, goggles and protective clothing.
-Avoid contact with oxidants during storage and handling to prevent dangerous reactions.
-In case of misuse or inhalation, seek medical attention immediately and show the relevant safety data sheet.
