These common heterocyclic compound, 1072-63-5, name is 1-Vinyl-1H-imidazole, its 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. Product Details of 1072-63-5
General procedure: Bis-vinylimidazolium bromoethane ([CnDVIM]Br) were synthesized by the reaction between 1-vinylimidazole and (CH2)2Br2, (CH2)4Br2, or (CH2)8Br2 [20]. Typically, 1-vinylimidazole (4.20g, 44.6mmol) and (CH2)nBr2 (21.7mmol) were dissolved in 5.0mL methanol. Then, the mixture was continuously magnetic stirred for 5min to get a homogenous solution and poured into a 50mL single-necked flask. After aerated nitrogen for about 3min, the flask was sealed and placed into 65C oil bath with a continuously magnetic stirring for 24h. After cooling to room temperature, excess diethyl ether (200mL) was poured into the solution and the crude salt was obtained. The obtained salt was washed with diethyl ether three times and dried under vacuum to get the yellow [CnDVIM]Br.
The synthetic route of 1-Vinyl-1H-imidazole has been constantly updated, and we look forward to future research findings.
