It is a toxic, colorless, and pyrophoric gas with a repulsively sweet odor. Diborane is a key boron compound with a variety of … See more Extensive studies of diborane have led to the development of multiple synthesis routes. Most preparations entail reactions of hydride donors with boron halides or alkoxides. The industrial synthesis of diborane involves the reduction of BF3 by sodium hydride See more Diborane and its variants are central organic synthesis reagents for hydroboration. Alkenes add across the B–H bonds to give … See more Because of the exothermicity of its reaction with oxygen, diborane has been tested as a rocket propellant. Complete combustion is … See more The structure of diborane has D2h symmetry. Four hydrides are terminal, while two bridge between the boron centers. The lengths of the B–Hbridge bonds and the B–Hterminal bonds are 1.33 and 1.19 Å respectively. This difference in bond … See more Diborane is a highly reactive and versatile reagent. Air, water, oxygen As a See more Diborane was first synthesised in the 19th century by hydrolysis of metal borides, but it was never analysed. From 1912 to 1936, Alfred Stock, the major pioneer in the chemistry of boron … See more
