Boron hydride clusters are compounds with the formula B x H y or related anions, where x ≥ 3. Many such cluster compounds are known. Common examples are those with 5, 10, and 12 boron atoms. Although they have few practical applications, the borane hydride clusters exhibit structures and bonding that differs strongly from the patterns seen in ...
A borane is a compound with the formula BR x H y although examples include multi-boron derivatives. A large family of boron hydride clusters is also known. In addition to some applications in organic chemistry , the boranes have attracted much attention as they exhibit structures and bonding that differs strongly from the patterns seen in ...
Borane makes a strong adduct with triethylamine; using this adduct requires harsher conditions in hydroboration. This can be advantageous for cases such as hydroborating trienes to avoid polymerization. More sterically hindered tertiary and silyl amines can deliver borane to alkenes at room temperature. Borane(5) is the dihydrogen complex of
The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger boranes all consist of boron clusters that are polyhedral, some of which exist as isomers. For example, isomers of B 20 H 26 are based on the fusion of two 10-atom clusters.
Pentaborane(9) is an inorganic compound with the formula B 5 H 9.It is one of the most common boron hydride clusters, although it is a highly reactive compound.Because of its high reactivity with oxygen, it was once evaluated as rocket or jet fuel.
One example is thexylborane (ThxBH 2), produced by the hydroboration of tetramethylethylene: [6] A chiral example is monoisopinocampheylborane. Although often written as IpcBH 2, it is a dimer [IpcBH 2] 2. It is obtained by hydroboration of (−)‐α‐pinene with borane dimethyl sulfide. [7] Dialkylboranes are also rare for small alkyl groups.
The simplest borane is diborane, or B 2 H 6. [5] Another example is B 10 H 14. The next group-13 elements, aluminium and gallium, form fewer stable hydrides, although both AlH 3 and GaH 3 exist. Indium, the next element in the group, is not known to form many hydrides, except in complex compounds such as the phosphine complex H 3 InP(Cy) 3 (Cy ...
Hexaborane, also called hexaborane(10) to distinguish it from hexaborane(12) (B 6 H 12), is a boron hydride cluster with the formula B 6 H 10. It is a colorless liquid that is unstable in air. It is a colorless liquid that is unstable in air.
