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]
The rule defines boranes to have four types of bonds besides the terminal B-H bonds: [2] The structures assigned to the letters s, t, y, and x. Where: B-H-B bonds are 3c-2e bonds, taking up three orbitals and two valence electrons. B-B-B bonds are 3c-2e bonds, taking up three orbitals and two valence electrons.
Alfred Stock invented the glass vacuum line for this purpose. [2] The structure of diborane was correctly predicted in 1943 many years after its discovery. [3] Interest in boranes increased during World War II due to the potential of uranium borohydride for enrichment of the uranium isotopes and as a source of hydrogen for inflating weather ...

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 ...
This bonding pattern is also seen in trimethylaluminium, which forms a dimer Al 2 (CH 3) 6 with the carbon atoms of two of the methyl groups in bridging positions. This type of bond also occurs in carbon compounds, where it is sometimes referred to as hyperconjugation; another name for asymmetrical three-center two-electron bonds.
