2879-20-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, cas is 2879-20-1,the benzodioxans compound, it is a common compound, a new synthetic route is introduced below.
The 178mg (1mmol) 6- acetyl-1,4-benzo-dioxane, 80mg (2mmol) sodium hydroxide was placed in 50mLSingle neck flask was added 10mL of ethanol and dissolved; the 280mg (0.97mmol) 2- fluoro -4- (9- (9H- carbazol-yl))Benzaldehyde was dissolved in 10mL of dichloromethane, ethanol and added dropwise to the mixture, stirred at room temperature overnight, filtered,Ethanol, washed with petroleum ether and dried to give a pale yellow solid (LJZ-6-18) 386mg, 89% yield.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, 2879-20-1
