Recommanded Product: 1452-77-3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Picolinamide, is researched, Molecular C6H6N2O, CAS is 1452-77-3, about Activation of nitriles by silver(I) N-heterocyclic carbenes: An efficient on-water synthesis of primary amides. Author is Thirukovela, Narasimha Swamy; Balaboina, Ramesh; Kankala, Shravankumar; Vadde, Ravindhar; Vasam, Chandra Sekhar.
A first example of silver(I) N-heterocyclic carbene (Ag(I)-NHC) catalyzed on-water synthesis of primary amides by hydration of nitriles under mild reaction conditions was described. This organometallic catalytic system has excellent tolerance for various homo-aromatic, hetero-aromatic and aliphatic nitriles to afford primary amides in good yields in neat water.
