In an article, author is Elmi-Mehr, Maryam, once mentioned the application of 643-79-8, Recommanded Product: Benzene-1,2-dicarboxaldehyde, Name is Benzene-1,2-dicarboxaldehyde, molecular formula is C8H6O2, molecular weight is 134.132, MDL number is MFCD00003335, category is phthalazine. Now introduce a scientific discovery about this category.
An efficient and environmentally friendly procedure for the synthesis of 3-amino-1-aryl-5, 10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b] phthalazine-2-carbonitriles through the one-pot, three-component reaction of phthalhydrazide, an aromatic aldehyde, and malononitrile in the presence of cellulose sulfuric acid (cellulose-SO3H) is described. The reactions occur under thermal solvent-free conditions and the process is operative with various aromatic aldehydes, giving the corresponding products in high yields. Other beneficial features of this protocol include inexpensive, biodegradable and easily obtained catalyst, avoiding the use of harmful organic solvents, simple work-up, and the recyclability and reusability of the catalyst for up to five consecutive runs.
If you are interested in 643-79-8, you can contact me at any time and look forward to more communication. Recommanded Product: Benzene-1,2-dicarboxaldehyde.
