Reference of 7766-50-9,Some common heterocyclic compound, 7766-50-9, name is 11-Bromo-1-undecene, molecular formula is C11H21Br, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: p-Benzenediol (Hydroquinone, defined as BP1 here) (2.2 g,20 mmol) and sodium hydroxide (2.4 g, 60 mmol) were dissolved in 120 mL DMF in a 250-mL round bottomed Schlenk flask, then themixture was stirred for 30 min, and a solution of 11-bromo-1-undecene (12 g, 51.5 mmol) in DMF (120 mL) was added dropwise over 10 min. The resulting reaction mixture was heated at 70 C and left stirring for more than 8 h. Subsequently, the reaction was cooled to RT and quenched with addition of diethyl ether (100 mL) and water (100 mL). The aqueous phase was extracted with diethyl ether (300 mL 2), and the combined organic fractions were washed with brine and dried over MgSO4 and concentrated. The residue was recrystallized from EtOH twice to obtain 6.1 g BP1-M1. Yield: 74%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 11-Bromo-1-undecene, its application will become more common.
