Synthesis, p. 511, 1987 DOI: 10.1055/s-1987-27988 | | General Description | 11-Bromo-1-undecene is a halogenated hydrocarbon. It can be synthesized by employing alkenyl esters or dibromides as starting materials. | | Synthesis | General procedure for the synthesis of 1-bromo-10-undecene from 10-undecadecen-1-ol: To a dichloromethane solution of 10-undecadecen-1-ol (200 mg, 1.17 mmol) was added sequentially at 0 °C CBr4 (403 mg, 1.29 mmol, 1.1 eq.) and Ph3P (340 mg, 1.29 mmol, 1.1 eq. ). The reaction mixture was kept stirred at 0 °C for 2 hours. After completion of the reaction, the reaction was quenched by the addition of water. The reaction mixture was extracted with dichloromethane, the organic layers were combined and dried over anhydrous Na2SO4. The organic solvent was removed by concentration under reduced pressure to give the crude product. The crude product was used directly in the next step of the reaction without chromatographic purification. Purification of the crude product by silica gel column chromatography afforded 1-bromo-10-undecene (273 mg, quantitative yield) [56] as a colorless oil. | | References | [1] Synthetic Communications, 1984, vol. 14, # 7, p. 591 - 598
