C6H5BH2

C6H5BH2, also known as phenylborane, is an organoboron compound with the chemical formula C6H5BH2. It consists of a phenyl group (C6H5) directly bonded to a borane group (BH2). This molecule can be considered a substituted borane, where one hydrogen atom of diborane (B2H6) has been replaced by a phenyl group. Phenylborane is a colorless liquid under standard conditions.

This compound is of interest in organometallic chemistry and synthetic organic chemistry. It can serve as a precursor for various boron-containing compounds and can participate in reactions typical of boranes, such as hydroboration and oxidation. The phenyl group imparts some solubility in organic solvents and influences the reactivity of the boron center. Phenylborane is a relatively reactive species and is often handled under an inert atmosphere to prevent decomposition or unwanted reactions with air and moisture. It can be synthesized through various methods, often involving the reaction of phenyl Grignard reagents with boron halides. Due to its reactivity, specific handling precautions are necessary when working with phenylborane. Its applications are primarily in research settings for the synthesis of more complex molecules.
