14900-39-1 - Introduction
1-Phenylvinylboronic acid is an organic boron compound with the formula C8H9BO2. It is a colorless crystalline solid, stable at room temperature.
Nature:
1-Phenylvinylboronic acid is slightly soluble in water and can be dissolved in organic solvents. It has a melting point of about 136-140 ° C. And is less volatile. It is a relatively stable compound and can be stored for a long time under certain conditions.
Use:
1-Phenylvinylboronic acid can be used as an important intermediate in organic synthesis. It can participate in a variety of organic reactions, such as alcoholization, alkyd, hydrogenation, olefin reaction. Because its Organoboron contains stable π-π self-crosslinking ability, it can be used in optoelectronic materials, fluorescent labeling reagents, organometallic catalysis and other fields.
Method:
1-Phenylvinylboronic acid can be prepared by reacting a Grignard reagent with an aromatic aldehyde. The specific preparation method can first synthesize Grignard reagent with phenylacetylene and potassium tert-butoxide, and then react with aromatic aldehyde to produce 1-Phenylvinylboronic acid.
Safety Information:
1-Phenylvinylboronic acid will not cause obvious harm to the human body under general operating conditions, but it is still necessary to pay attention to safe operation. When in use, wear appropriate personal protective equipment to avoid contact with skin and eyes. If it comes into contact with skin, rinse immediately with plenty of water. If inhaled or ingested, seek medical attention immediately. Avoid contact with harmful substances such as oxidants and acids during storage, and keep away from open flames and high temperatures.
