Safety of Sodium tetraphenylborate, We’ll be discussing some of the latest developments in chemical about CAS: 143-66-8, Name is Sodium tetraphenylborate, SMILES is C1([B-](C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4)=CC=CC=C1.[Na+], belongs to phthalazine compound. In a article, author is Elmi-Mehr, Maryam, introduce new discover of the 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.
