Clear colorless to yellow liquid | [Uses]
5-Bromo-1-pentene is widely utilized in the stereoselective synthesis of 7alpha-(3-carboxypropyl) estradiol. It plays an important role as starting material in the synthesis of a variety of compounds including DL-histrionicotoxin and benzophenone containing fatty acids. | [Synthesis Reference(s)]
Tetrahedron, 28, p. 675, 1972 DOI: 10.1016/0040-4020(72)84031-6 | [Synthesis]
1,5-Dibromopentane (100 Kg), N, N-dimethylformamide (100 Kg), and hexamethylphosphoramide (6.2 Kg) were stirred and mixed, and then heated in an oil bath at 140°C for 4 h. Atmospheric distillation collects the fractions, and the collected fractions are washed twice with 100 Kg brine. The organic liquid is distilled to obtain product 5-Bromo-1-pentene.
