Spectral characterization and crystal structure of 2-benzoylpyridine nicotinoyl hydrazone

Chemoselective Reactivity Study of 6-Hydrazinonicotinic Acid Hydrazide

“…4,5 The pyridine 1 reacted with equimolar amounts of commercially available ferrocene carboxaldehyde 2a or acetylferrocene 2b to give 3a-b in 72 -77% yields. In a subsequent step, hydrazones 3 reacted with β-alkoxyvinyl trifluoromethyl ketones 4 in ethanol under reflux, to give in 4 hours pyrazolyl-pyridine ferrocenyl hydrazone 5.…”

Six coordinate Ni(II) complexes of ONN donor aroylhydrazone ligands: synthesis, spectral studies, and crystal structures

“…Synthesis of ligands and the Ni(II) complexes HL 1 and HL 2 : The structures of the ligands are given in Fig 1. The ligand HL 1 was synthesized as described in literature [13]. HL 2 was synthesized by adapting an earlier reported procedure [17].…”

“…The antibacterial [7][8][9], antimicrobial [10] and antineoplastic [11,12] activities displayed by the coordination compounds of hydrazones have led to their extensive study. In continuation of our work on the synthesis and characterization of aroyl hydrazones and their coordination compounds [13][14][15][16], we now report a new aroyl hydrazone ligand and two new Ni(II) complexes. In addition to the azomethine nitrogen and carbonyl oxygen, the coordinating capacity of the ligand has been enhanced by the presence of coordinating nitrogen in the pyridyl ring of aromatic ketone.…”

Transition Metal Complexes of (E)-N’-(4-cyanobenzylidene)nicotinohydrazide): Synthesis, Structural and Anti-Mycobacterial Activity Study

“…Applied Sci., 15 (10): 1210Sci., 15 (10): -1222Sci., 15 (10): , 2015 physical and chemical properties. Several reviews on hydrazones have shown that most of them are flexible in terms of their coordinating ability (Tripathi et al, 2011;Kuriakose et al, 2007;Ray et al, 2008). They have a minimum of two coordinating groups, the amine and the carbonyl moieties.…”
