Conformation and electrochemistry of some β-[alkyl-bridged biferrocenyl]-α,β-unsaturated ketones

Ternary copper(II) complexes of aroylhydrazones and mono/bidentate heterocycles with different structures: synthesis, crystal structure and properties

“…Aroylhydrazones with several coordination sites can act as neutral or monoanionic bidentate or tridentate ligands depending on the substituents and the reaction conditions [4,5]. Coordination to metals either in keto(I) or enol(I) tautomeric forms make them attractive as ligand [5][6][7][8][9][10][11][12][13][14]. Imidazole is a biologically important ligand, monodentate at low pH and bridging at higher pH.…”

Synthesis, structure and electrochemical behaviour of 2,2-diferrocenylpropane-substituted dihydropyrazole derivatives

“…The net charges on two iron atoms Fe1 and Fe2 of DFP moiety are 0.099 and 0.112, respectively, while that on Fe3 is 0.114. According to the literature [10,11], more net charges on iron atom lead to higher oxidation potential of the ferrocene unit the iron situated. For 5a, it can be inferred from Fig.…”

Preparation, characterization, crystal structure and bioactivity determination of ferrocenyl–thiazoleacylhydrazones

“…[7 -10] Hydrazide-hydrazones, which are readily obtained by the condensation of aldehydes or ketones with hydrazines in the presence of an acid catalyst, represent a class of azomethine compounds. [11,12] Hydrazide-hydrazones have been demonstrated to possess antibacterial, [13 -15] anti-HIV-1, [16 -18] anticonvulsant [19,20] and antitubercular [21,22] activities.…”
