  3. Bromopentane - Wikipedia

    en.wikipedia.org/wiki/Bromopentane

    Bromopentanes are a group of bromoalkanes consisting of pentane isomers with one or more hydrogen atoms replaced by bromine atoms. They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids.

  4. Topicity - Wikipedia

    en.wikipedia.org/wiki/Topicity

    Enantiotopic groups are identical and indistinguishable except in chiral environments. For instance, the CH 2 hydrogens in ethanol (CH 3 CH 2 OH) are normally enantiotopic, but can be made different (diastereotopic) if combined with a chiral center, for instance by conversion to an ester of a chiral carboxylic acid such as lactic acid, or if coordinated to a chiral metal center, or if ...

  5. 2-Bromopentane - Wikipedia

    en.wikipedia.org/wiki/2-Bromopentane

    2-Bromopentane is a bromoalkane and isomer of bromopentane. It is a colorless liquid. 2-Bromopentane is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-2-bromopentane and ( S )-2-bromopentane, or as a racemic 1:1 mixture of the two enantiomers .

  6. Transfer hydrogenation - Wikipedia

    en.wikipedia.org/wiki/Transfer_hydrogenation

    It uses hydrogen donor compounds such as formic acid, isopropanol or dihydroanthracene, dehydrogenating them to CO 2, acetone, or anthracene respectively. [1] Often, the donor molecules also function as solvents for the reaction. A large scale application of transfer hydrogenation is coal liquefaction using "donor solvents" such as tetralin. [2 ...

  7. Enantioselective reduction of ketones - Wikipedia

    en.wikipedia.org/wiki/Enantioselective_reduction...

    Formic acid and formate salts may also be used as reductants in transfer hydrogenations. Simple aryl ketones are reduced enantioselectively when a chiral amino alcohol ligand is employed. [4] (9) Transition metal catalysts have also been used with hydrogen gas as the stoichiometric reductant.

  8. Asymmetric carbon - Wikipedia

    en.wikipedia.org/wiki/Asymmetric_carbon

    In stereochemistry, an asymmetric carbon is a carbon atom that is bonded to four different types of atoms or groups of atoms. [1] [2] The four atoms and/or groups attached to the carbon atom can be arranged in space in two different ways that are mirror images of each other, and which lead to so-called left-handed and right-handed versions (stereoisomers) of the same molecule.

  9. Bromine compounds - Wikipedia

    en.wikipedia.org/wiki/Bromine_compounds

    H 3 PO 3 + H 2 O + Br 2 → 2 HBr + H 3 PO 4. At room temperature, hydrogen bromide is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative bromine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen ...
