WebDiborane (6), generally known as diborane, is the chemical compound with the formula B 2 H 6. It is a toxic, colorless, and pyrophoric gas with a repulsively sweet odor. Diborane is a key boron compound with a variety of applications. It has attracted wide attention for its electronic structure. Several of its derivatives are useful reagents. A boronic acid is an organic compound related to boric acid (B(OH)3) in which one of the three hydroxyl groups (−OH) is replaced by an alkyl or aryl group (represented by R in the general formula R−B(OH)2). As a compound containing a carbon–boron bond, members of this class thus belong to the larger class of organoboranes.
