Diborane(4) is a transient inorganic compound with the chemical formula B 2 H 4.Stable derivatives are known. Diborane(4) has been produced by abstraction of two hydrogen atoms from diborane(6) using atomic fluorine and detected by photoionization mass spectrometry. [1]
Diborane(6), commonly known as diborane, is the chemical compound with the formula B 2 H 6.It is a highly toxic, colorless, and pyrophoric gas with a repulsively sweet odor. . Given its simple formula, borane is a fundamental boron compou
The development of the chemistry of boranes led to innovations in synthetic methods as well as structure and bonding. First, new synthetic techniques were required to handle diborane and many of its derivatives, which are both pyrophoric and volatile.
The styx rule, also known as Lipscomb's styx rule, can be used to calculate the structures of boranes.It was developed by William Lipscomb in 1954. [1] The rule defines boranes to have four types of bonds besides the terminal B-H bonds: [2]
[4] [5] An extended version of this model is used to describe the whole class of hypervalent molecules such as phosphorus pentafluoride and sulfur hexafluoride as well as multi-center π-bonding such as ozone and sulfur trioxide. There are also molecules such as diborane (B 2 H 6) and dialane (Al 2 H 6) which have three-center two-electron bond ...

The heavier tetrahalodiboranes, B 2 Br 4 and B 2 I 4, were first published in 1949 by Schlesinger et al. and Schumb respectively. [10] B 2 Br 4 was first accessed by reacting B 2 Cl 4 and BBr 3. [10] B 2 I 4 was first synthesized using electrodeless radiofrequency discharge to reduce BI 3. [10] B 2 Br 4 is stable at temperatures below -40 °C ...
