  2. Butyl group - Wikipedia

    en.wikipedia.org/wiki/Butyl_group

    If it connects at one of the non-terminal (internal) carbon atoms, it is secondary butyl or sec-butyl: −CH(CH 3)−CH 2 −CH 3 (preferred IUPAC name: butan-2-yl) The second isomer of butane, isobutane, can also connect in two ways, giving rise to two additional groups:

  3. Triisobutylaluminium - Wikipedia

    en.wikipedia.org/wiki/Triisobutylaluminium

    The equilibrium constant, K D, is 3.810 at 20 °C. [3] 2 Al(CH 2 CH(CH 3) 2) 3 [Al(CH 2 CH(CH 3) 2) 3] 2. In the dimer, the bridging carbon-aluminium bond is elongated and exhibits evidence of restricted rotation. For the sake of simplicity, TiBA is written as the monomer in this article.

    (5) The use of silyl acetylenes avoids the problem of competitive metalation of terminal alkenes. The stereoselectivity of hydroalumination can be altered through a change in solvent: tertiary amine solvents provide the cis alkenylalane and hydrocarbon solvents provide the trans isomer.

  6. Diisobutylaluminium hydride - Wikipedia

    en.wikipedia.org/wiki/Diisobutylaluminium_hydride

    DIBAL can be prepared by heating triisobutylaluminium (itself a dimer) to induce β-hydride elimination: [3] (i-Bu 3 Al) 2 → (i-Bu 2 AlH) 2 + 2 (CH 3) 2 C=CH 2. Although DIBAL can be purchased commercially as a colorless liquid, it is more commonly purchased and dispensed as a solution in an organic solvent such as toluene or hexane.

    Triethylaluminium can be formed via several routes. The discovery of an efficient route was a significant technological achievement. The multistep process uses aluminium, hydrogen gas, and ethylene, summarized as follows: [4]

  9. Butyl rubber - Wikipedia

    en.wikipedia.org/wiki/Butyl_rubber

    The formula for PIB is: –(–CH 2 –C(CH 3) 2 –) n – The formula for IIR is: It can be made from the monomer isobutylene (CH 2 =C(CH 3) 2) only via cationic addition polymerization. A synthetic rubber, or elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubber.
