253-52-1, 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. Phthalazine, cas is 253-52-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
Specific preparation methods are: no special protection, clean air to a single-necked flask were added sequentially magneton, phthalazine(52mg, 0.4mmol), was added sodium iodide (18mg, 30molpercent), 70percent of the mass fraction of the water phase of t-butyl hydroperoxide(152mg, 1.2mmol), then add toluene (728.8mg, 8mmol), toluene as both reactant and as a solvent, the reaction at 150 1Hours TLC showed the starting material is completely consumed phthalazine. Heating was stopped to quench the reaction. Without extraction, direct wetLoading, 200-300 mesh silica gel column chromatography, a mixed solvent of ethyl acetate and petroleum ether (1: 4) rinse. Separated structure of formula IXaFormula compound 84.0mg, 89percent yield;
The chemical industry reduces the impact on the environment during synthesis,253-52-1,Phthalazine,I believe this compound will play a more active role in future production and life.
