Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1452-77-3, is researched, Molecular C6H6N2O, about Amidation of aldehydes using mono-cationic half-sandwich rhodium(III) complexes with functionalized phenylhydrazone ligands, the main research direction is rhodium half sandwich phenylhydrazone cationic preparation amidation catalyst aldehyde; crystal structure mol rhodium half sandwich phenylhydrazone complex cation.Reference of Picolinamide.
A series of mono-cationic half-sandwich rhodium(III) complexes have been synthesized in methanol using phenylhydrazone-derived ligands (L1-L6) and the starting precursor [(η5-C5Me5)2Rh2(μ-Cl)2Cl2] in a 2:1 molar ratio. The N,N’-phenylhydrazone complexes have been isolated as tetraphenylborate salts. All complexes were characterized by elemental anal., FT-IR, UV-visible, NMR spectroscopy and mass spectrometry. The mol. structure of complex [(η5-C5Me5)Rh(L1)Cl](BPh4) (1) was confirmed by single-crystal X-ray structure anal. Complex [(η5-C5Me5)Rh(L3)Cl](BPh4) (3) was used as an efficient catalyst for the amide formation reaction, with up to 99% conversion after 2 h in toluene at 110 °C in the presence of hydroxyl amine hydrochloride and sodium bicarbonate.
The article 《Amidation of aldehydes using mono-cationic half-sandwich rhodium(III) complexes with functionalized phenylhydrazone ligands》 also mentions many details about this compound(1452-77-3)Reference of Picolinamide, you can pay attention to it, because details determine success or failure
