119-39-1, 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. Phthalazin-1(2H)-one, cas is 119-39-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
1-(2H)-pyridazinone 1.00 g (6.84 mmol) and triphenylphosphine 1.79 g (6.84 mmol) were added to 25 ml of tetrahydrofuran, and 0.85 g (6.84 mmol) of 2-bromoethanol was added dropwise in an ice bath.After the dropwise addition was completed, 1.22 g (7.00 mmol) of diethyl azodicarboxylate was added dropwise to the ice bath.After stirring for 1 hour in an ice bath, the reaction was carried out at room temperature until TLC followed the progress of the reaction.The solvent was evaporated under reduced pressure. EtOAc EtOAc m.The product was obtained as a reddish brown solid, 1.01 g, yield 58%.
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 Phthalazin-1(2H)-one, 119-39-1
