Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Category: phthalazines, 81-16-3, Name is 2-Aminonaphthalene-1-sulfonic acid, molecular formula is C10H9NO3S, belongs to phthalazines compound. In a document, author is Wang Wang, introduce the new discover.
An improved procedure for the three-component synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives using basic ionic liquid
An efficient and green method for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been achieved through the one-pot, three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate, and phthalhydrazide in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) as catalyst in EtOH. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid can be recovered and recycled for subsequent reactions. Moreover, this protocol has the advantages of easy work-up, short reaction time, mild reaction conditions and environmentally benign procedures compared with the reported methods.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 81-16-3. Category: phthalazines.
