Phenylboronic acid Chemical Properties,Usage,Production
Chemical Properties
white to light yellow crystal powder. Insoluble in water and benzene, easily soluble in ether and methanol. When exposed to air or under heating conditions, it is easy to dehydrate and form a three-molecular polymer.
Uses
Phenylboronic acid and its derivatives form complexes with polyol compounds such as saccharides and poly(vinyl alcohol) (PVA). Glucose-sensitive hydrogels can be prepared by using phenylhoronic acid as a ligand for target glucose. For example. a copolymer with phenylboronic acid moieties was synthesized by copolymerization of 4V-vinyl-2-pyrrolidone (NVP) and 3-(acryl- amide)phcnylhoronic acid (PBA). The complexes between the NVP-PBA copolymer and PVA enable us to construct glucose-sensitive insulin release systems because the complexes dissociated in response to the glucose concentration.
This phenylboronic acid is soluble in water and the coupling reaction can even be carried out in water. It is compatible with many organic substituents such as esters, ketones, alcohols, etc. which would prohibit the use of Grignard reagents in coupling reactions.
Uses
Phenylboronic Acid is a compound used in organic synthesis of various pharmaceutical goods.
Phenylboronic acid (PBA) and its derivatives can bind sugars and other diol compounds to form cyclic boronate esters. These esters bear negative charges. Due to this reaction, sugars can be detected by means of electrochemical and optical techniques.
PBA modified electrodes have been constructed as reagentless electrochemical sensors. There, PBA is absorbed on the electrode surface either as a self- assembled monolayer film ore a polymer thin film. Basically, for optical detection techniques for the detection of sugars, PBA is modified with a chromophore that should change its properties on reaction with a sugar.

General Description
Phenylboronic acid (PBA) is an organoboronic acid. It behaves as a molecular receptor that can attach to compounds containing cis-diol group. Microwave-assisted Suzuki coupling of aryl chlorides with phenylboronic acid in the presence of Pd/C (catalyst) and water (solvent) has been described. Palladium-catalyzed cross-coupling reaction of phenylboronicacid with haloarenes to afford biaryls has been reported.
Safety Profile
Poison by intravenous andintraperitoneal routes. Moderately toxic by ingestion.Mildly toxic by skin contact. When heated to decomposition it emitsacrid smoke and irritating fumes.
