  2. Bromocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Bromocyclohexane

    A mixture of cis-decalin and CXB can simultaneously match optical index and density of PMMA. [1] Due to the moderate dielectric constant of CXB (ε = 7.9 [2]), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide), leading to a very good approximation of colloidal hard sphere. [3]

  3. trans-1,2-Diaminocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Trans-1,2-Diaminocyclohexane

    trans-1,2-Diaminocyclohexane is an organic compound with the formula C 6 H 10 (NH 2) 2. This diamine is a building block for C 2-symmetric ligands that are useful in asymmetric catalysis. [1] A mixture of all three stereoisomers of 1,2-diaminocyclohexane is produced by the hydrogenation of o-phenylenediamine.

  4. Cyclohexane conformation - Wikipedia

    trans-1,3-Disubstituted cyclohexanes are like cis-1,2- and cis-1,4- and can flip between the two equivalent axial/equatorial forms. [ 2 ] Cis -1,4-Di- tert -butylcyclohexane has an axial tert -butyl group in the chair conformation and conversion to the twist-boat conformation places both groups in more favorable equatorial positions.

  5. Cyclohexa-1,3-diene - Wikipedia

    Cyclohexa-1,3-diene is an organic compound with the formula (C 2 H 4)(CH) 4. It is a colorless, flammable liquid. It is a colorless, flammable liquid. Its refractive index is 1.475 (20 °C, D).

  6. Cyclohexene - Wikipedia

    en.wikipedia.org/wiki/Cyclohexene

    Cyclohexene is a hydrocarbon with the formula (CH 2) 4 C 2 H 2. It is an example of a cycloalkene. At room temperature, cyclohexene is a colorless liquid with a sharp odor. Among its uses, it is an intermediate in the commercial synthesis of nylon. [3]

  7. 1,2-Diaminocyclohexane - Wikipedia

    en.wikipedia.org/wiki/1,2-Diaminocyclohexane

    1,2-Diaminocyclohexane (DACH) is an organic compound with the formula (CH 2) 4 (CHNH 2) 2. It is a mixture of three stereoisomers: cis-1,2-diaminocyclohexane and both enantiomers of trans-1,2-diaminocyclohexane. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH.

  8. Grob fragmentation - Wikipedia

    en.wikipedia.org/wiki/Grob_fragmentation

    The original work by Grob (1955) concerns the formation of 1,5-hexadiene from cis- or trans-1,4-dibromocyclohexane by sodium metal: [1] Grob fragmentation 1955. According to reviewers Prantz and Mulzer (2010), the name Grob fragmentation was chosen "in more or less glaring disregard of the earlier contributions". [6]
