Most 1-bromoalkanes are prepared by free-radical addition of hydrogen bromide to the 1-alkene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo derivative. [2] 1-Bromohexane undergoes reactions expected of simple alkyl bromides. It can form Grignard reagents. [3]
Cyclohexylbenzene is produced by the acid-catalyzed alkylation of benzene with cyclohexene. [1] [2] The process can proceed using benzene as the exclusive organic precursor.. Its partial hydrogenation gives cyclohexene, which alkylates the unhydrogenated benz
1-Bromobutane is the precursor to n-butyllithium: [4] 2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu.
Further, piracetam is not a concentrate, metabolite, constituent, extract or combination of any such dietary ingredient.

The enantioselective synthesis was accomplished by J. K. Whitesell by adding Pseudomonas fluorescens lipase to racemic trans-2-phenylcyclohexyl chloroacetate. [1] [2] This enzyme is able to hydrolyze the ester bond of the (−)-enantiomer but not the (+)-enantiomer.
