Nature:
4-Chloro-3-fluorophenylboronic acid is a colorless or pale yellow crystal with low solubility. It is an acidic compound, soluble in organic solvents such as ethanol and dimethyl ketone, but insoluble in water.
Use:
4-Chloro-3-fluorophenylboronic acid is often used as a catalyst in organic synthesis reactions, especially in Suzuki coupling reactions. It can catalyze the coupling reaction between boronic acids of aromatic compounds and organic halides to form new carbon-carbon bonds. This reaction is widely used in the fields of drug synthesis, material chemistry and pesticide synthesis.
Preparation Method:
4-Chloro-3-fluorophenylboronic acid can be obtained by reacting phenylboronic acid with chlorofluoroalkane. The specific synthesis method can be adjusted according to the laboratory conditions and the desired yield.
Safety Information:
When using 4-chloro-3-fluorophenylboronic acid, it is necessary to pay attention to safe operation. Because it is an irritant substance, it may cause irritation to the eyes, skin and respiratory tract. Wear appropriate protective gloves, glasses and a protective mask during use.
