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 applications. It has attracted wide attention for its electronic structure. Several of its derivatives are … 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 … 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 was first synthesised in the 19th century by hydrolysis of metal borides, but it was never analysed. From 1912 to 1936, Alfred Stock, … See more Diborane is a pyrophoric gas. Commercially available adducts are typically used instead, at least for applications in … See more Diborane is a highly reactive and versatile reagent. Air, water, oxygen As a 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 strongly exothermic. However, … See more synthesis of literature review
