A new synthetic route of 1452-77-3

Although many compounds look similar to this compound(1452-77-3)Reference of Picolinamide, numerous studies have shown that this compound(SMILES:O=C(N)C1=NC=CC=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.

Reference of Picolinamide. 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 Appraisal of Ruthenium(II) complexes of (4-phenoxyphenylazo) ligands for the synthesis of primary amides by dint of hydroxylamine hydrochloride and aldehydes. Author is Vinoth, Govindasamy; Indira, Sekar; Bharathi, Madheswaran; Sounthararajan, Muniyan; Sakthi, Dharmalingam; Bharathi, Kuppannan Shanmuga.

A new family of O, N donor-functionalized (4-phenoxyphenylazo)-2-naphthol/4-substituted phenol-based ligands (HL1-HL4) has been synthesized. The prepared ligands were successfully utilized for the access of a series of ruthenium(II) carbonyl complexes of the type [Ru(L)Cl(CO)(EPh3)3] (E = phosphine/arsine), (L = 1-(4-phenoxyphenylazo)-2-naphthol (HL1), 2-(4-phenoxyphenylazo)-4-chlorophenol (HL2), 2-(4-phenoxyphenylazo)-4-methylphenol (HL3) and 2-(4-phenoxyphenylazo)-4-methoxyphenol (HL4)). All of the ruthenium(II) carbonyl complexes and ligands have been fully characterized by FT-IR, UV-visible, 1H NMR, 31P NMR, mass spectrometry and CHN anal. The ligands have been analyzed by 13C NMR. The UV-visible spectroscopic study reveals that both the ligands and Ru(II) complexes exhibit excellent charge transfer transitions. This is the basic criteria for the oxidative amidation reaction, which is an influential strategy for the transformation of oxygenated organic compounds to the profitable amides. However, this catalytic process makes more impact on the application of new divalent ruthenium(II) azo compounds as catalyst in a single-pot conversion of aldehydes to amides in the presence of NaHCO3.
