(3-CYANO-4-FLUOROBENZENE)BORONIC ACID - Introduction

acid is an organic compound with the chemical formula C7H5BFNO2. The following is a description of the properties, uses, preparation and safety information of the compound:

Nature:
-Appearance: colorless or slightly yellow crystal
-Solubility: Soluble in ethanol and dimethyl sulfoxide, slightly soluble in water
-Melting Point: about 140-143 ℃
-Stability: stable at room temperature, but avoid contact with strong oxidants

Use:
-acid is an important organic synthetic intermediate, usually as a derivative of Phenylboronic acid, which is widely used in organic synthetic chemical reactions.
-It can be used to introduce cyano and fluorine atoms into the target molecule for the synthesis of drugs, pesticides, functional materials and other organic compounds.

Method:
Li acid can be obtained by the reaction of Phenylboronic acid and 3-cyano-4-fluorophenyl sulfone. First, Phenylboronic acid was reacted with thionyl chloride to give Phenylboronic acid dichloroester, and then reacted with 3-cyano-4-fluorophenylsulfone under alkaline conditions to give acid.

Safety Information:
-The specific toxicity and safety information of acid is currently rarely reported, so it is necessary to pay attention to appropriate protective measures during use, such as wearing gloves, safety glasses and protective clothing.
