3939-23-9, 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.3939-23-9,3-Bromo-10H-phenothiazine, it is a common compound, a new synthetic route is introduced below.
2, under nitrogen protection will be prepared in step 1 p-phenylenediamine and phenothiazine derivatives according to 1:1 molar ratio was added to toluene, while adding potassium tert-butyl alcohol and palladium acetate as a catalyst,The reaction was heated to 80 C for 3 hours and then cooled to room temperature. The reaction was filtered,The filtrate was washed with dichloromethane and then the solvent was evaporated to dryness. The crude product was repeatedly washed with methanol and acetone,The product is obtained after purification by column chromatography.
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 3-Bromo-10H-phenothiazine reaction routes.
