Bromocyclopentane Usage And Synthesis

Chemical Properties

Bromocyclopentane is a colorless to light yellow liquid at standard temperature and pressure.

Uses

Bromocyclopentane, also known as Cyclopentyl Bromide, is an alkyl halide and a light yellow or colorless liquid at standard pressure and temperature. Bromocyclopentane is a precursor used in the preparation of cyclopentene and cyclopentanol. It is a fatty bromide, which is used as a solvent. It can be used an intermediate for the preparation of surfactant and pharmaceuticals and other organic compounds.

Reactions

Bromocyclopentane (22.0 g, 0.15 mol) was added to a soln of NaNO2 (18 g, 0.26 mol) in dry DMSO (100 mL) at 15 ℃ and the mixture was stirred at this temperature for 3 h. The mixture was poured into ice water (250 mL) and extracted with petroleum ether (bp 35-37 ℃; 4 × 50 mL). The combined organic extracts were washed with H2O (4× 50 mL), dried (MgSO4), and concentrated under reduced pressure. The residue was distilled to give Nitrocyclopentane; yield: 9.9 g (58%); bp 62 ℃/8 Torr; nD/20 1.4538.
