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 hydrides, undertook his research that led to the methods for the synthesis and handling of the highly reactive, volatile, and often … See more Diborane(6), generally known as diborane, is the chemical compound with the formula B2H6. 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. … See more Diborane and its variants are central organic synthesis reagents for hydroboration. Alkenes add across the B–H bonds to give … See more Diborane is a pyrophoric gas. Commercially available adducts are typically used instead, at least for applications in … 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 pyrophoric substance, diborane reacts exothermically See more Because of the exothermicity of its reaction with oxygen, diborane has been tested as a rocket propellant.
