1-Bromopentane; 2-Bromopentane [1] (chiral) 3-Bromopentane; There are four isomers of monobromopentane based on 2-methylbutane: 1-Bromo-2-methylbutane (chiral) 1-Bromo-3-methylbutane; 2-Bromo-2-methylbutane; 2-Bromo-3-methylbutane (chiral) 2,2-Dimethylpropane has only one monobrominated derivative, 1-bromo-2,2-dimethylpropane, also known as ...

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 .

Enantioselective ketone reductions convert prochiral ketones into chiral, non-racemic alcohols and are used heavily for the synthesis of stereodefined alcohols. [1]Carbonyl reduction, the net addition of H 2 across a carbon-oxygen double bond, is an important way to prepare alcohols.
The chiral fence. Chiral ligands work by asymmetric induction somewhere along the reaction coordinate. The image to the right illustrates how a chiral ligand may induce an enantioselective reaction. The ligand (in green) has C 2 symmetry with its nitrogen, oxygen or phosphorus atoms hugging a central metal atom (in red). In this particular ...
In discussing mechanisms of organic reactions, methyl lithium and related Grignard reagents are often considered to be salts of CH − 3; and though the model may be useful for description and analysis, it is only a useful fiction. Such reagents are generally prepared from the methyl halides: 2 M + CH 3 X → MCH 3 + MX. where M is an alkali metal.
The key property of organoboranes (R 3 B) and borates (R 4 B −, generated via addition of R − to R 3 B) is their susceptibility to reorganization. These compounds possess boron–carbon bonds polarized toward carbon. The boron-attached carbon is nucleophilic; [31] in borates, the nucleophicity suffices for intermolecular transfer to an ...
