  2. Boron hydride clusters - Wikipedia

    en.wikipedia.org/wiki/Boron_hydride_clusters

    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 ...

  3. Boranes - Wikipedia

    en.wikipedia.org/wiki/Boranes

    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 ...

  4. Borane - Wikipedia

    en.wikipedia.org/wiki/Borane

    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

  5. Organoboron chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoboron_chemistry

    Structure of a rare monomeric boron hydride, R = i-Pr. [4] The most-studied class of organoboron compounds has the formula BR n H 3−n. These compounds are catalysts, reagents, and synthetic intermediates. The trialkyl and triaryl derivatives feature a trigonal-planar boron center that is typically only weakly Lewis acidic.

  6. Boron monohydride - Wikipedia

    en.wikipedia.org/wiki/Boron_monohydride

    Boron monohydride can be formed from borane carbonyl exposed to ultraviolet light. BH 3 CO → BH + CH 2 O [2] Boron monohydride is formed when boron compounds are heated to a high temperature in the presence of hydrogen. [3] Boron monohydride is formed when the boron anion B − reacts with a hydrogen ion H +. It is also formed when atomic ...

  7. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    A large number of anionic boron hydrides are known, e.g. [B 12 H 12] 2−. The formal oxidation number in boranes is positive, and is based on the assumption that hydrogen is counted as −1 as in active metal hydrides. The mean oxidation number for the boron atoms is then simply the ratio of hydrogen to boron in the molecule.

  8. Decaborane - Wikipedia

    en.wikipedia.org/wiki/Decaborane

    It is commonly synthesized via the pyrolysis of smaller boron hydride clusters. For example, pyrolysis of B 2 H 6 or B 5 H 9 gives decaborane, with loss of H 2. [4] On a laboratory scale, sodium borohydride is treated with boron trifluoride to give NaB 11 H 14, which is acidified to release borane and hydrogen gas. [3]

  9. Polyhedral skeletal electron pair theory - Wikipedia

    en.wikipedia.org/wiki/Polyhedral_skeletal...

    In the special case of boron hydride clusters, each boron atom connected to 3 or more vertices has one terminal hydride, while a boron atom connected to two other vertices has two terminal hydrogen atoms. If more hydrogen atoms are present, they are placed in open face positions to even out the coordination number of the vertices.
