Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 31643-49-9, Name is 4-Nitrophthalonitrile, molecular formula is C8H3N3O2, belongs to nitriles-buliding-blocks compound, is a common compound. In a patnet, author is Shigeno, Masanori, once mentioned the new application about 31643-49-9, Product Details of 31643-49-9.
Catalytic C(sp(2))-C(sp(3)) Bond Formation of Methoxyarenes by the Organic Superbase t-Bu-P4
The organic superbase catalyst t-Bu-P4 achieves nucleophilic aromatic substitution of methoxyarenes with alkanenitrile pronucleophiles. A variety of functional groups [cyano, nitro, (non)enolizable ketone, chloride, and amide moieties] are allowed on methoxyarenes. Moreover, an array of alkanenitriles with/without an aryl moiety at the nitrile alpha-position can be employed. The system also features no requirement of a stoichiometric base, MeOH (not salt waste) formation as a byproduct, and the production of congested quaternary carbon centers.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 31643-49-9. The above is the message from the blog manager. Product Details of 31643-49-9.
