Properties of Phenylboronic acid


Product name: Phenylboronic acid
Description of Phenylboronic acid:
Properties:
Phenylboronic acid is soluble in most polar organic solvents and is poorly soluble in hexanes and carbon tetrachloride. This planar compound has idealized C2V molecular symmetry. The boron atom is sp2-hybridized and contains an empty p-orbital. The orthorhombic crystals use hydrogen bonding to form units made up of two molecules. These dimeric units are combined to give an extended hydrogen-bonded network. The molecule is planar with a minor bend around the C-B bond of 6.6o and 21.4o for the two PhB(OH)2 molecules.In 1860, the first borane synthesized was ethylboronic acid. Edward Frankland was the first to prepare and isolate this boronic acid using diethylzinc and triethylborate to produced triethylborane, which oxidized in air to ethylboronic acid.
