Synthesis, characterization and biological studies of ferrocenyl complexes containing thiophene moiety

Synthesis, structural characterization and electrochemical recognition of metal ions of two new ferrocenylhydrazone‐based receptors

“…[19 -26] It is known that ferrocenyl-bearing hydrazones can form stable complexes with various transition metal ions. [27,28] However, there has been limited study about their electrochemical sensing properties. Taking these into consideration, we synthesized two new ferrocenylhydrazonebased receptors, referred to from now on as FcL 1 and FcL 2 , respectively, reported in Scheme 1.…”

Characterization of Eu(III) Complex for Determination of Bumetanide in Pharmaceutical Preparations and in Biological Fluids

“…In complex 1 a broad band appeared in the range 3000-3600 cm −1 assigned to the water molecules and/or to the OH stretching vibration of the ligands and/or the ethanol molecules present in the complex (22)(23)(24) . The new bands at 505 cm -1 observed in complex 1 were attributed to M-O bond in complex 1 (25)(26)(27)(28)(29)(30)(31)(32) .…”

New lanthanide complexes of 1,1`-bis[(2-thienylmethylidene)hydrazono-1-ethyl]-ferrocene and 1,1`-bis(2,3-dihydro-2-methylbenzo[d]thiazol-2-yl)ferrocene: Synthesis, characterization and antimicrobial properties

“…1,1`-Diacetyl-ferrocene was prepared according to Rosenblum and Woodward method [18]. 1,1`-Bis[(2-thienylmethylidene) hydrazono-1-ethyl]-ferrocene (L 1 ) and 1,1`-bis(2,3-dihydro-2-methylbenzo[d]thiazol-2-yl)ferrocene (L 2 ) were synthesized and characterized as described in the literature [15,19]. Yields refer to analytically pure compounds and were not optimized.…”

“…The ligand L 1 , 1,1`-bis[(2-thienylmethylidene)hydrazono-1-ethyl]ferrocene was prepared by addition of 2-thiophenealdehyde to 1,1`-diacetylferrocene dihydrazone in ∼2:1 molar ratio in ethanol with reflux for 2h [15]. Characterization of the ligand L 1 was confirmed from the elemental analysis, IR, 1 H NMR and 13 C NMR spectra.…”

“…Ferrocene is nontoxic and has a unique structure as well as an excellent redox property, allowing wide applications in medicinal chemistry. These interesting applications of ferrocenyl compounds resulted in several reports of hetero-bimetallic complexes [14][15][16][17], since some ferrocenyl complexes showed enhanced biological activity compared to parent ligand. The aim of this work is to prepare a series of lanthanide complexes with two ferrocenyl ligands and to characterize the structure of these complexes.…”
