The self-assembly and structural characterization of the new ferrocene-containing dicopper(II) double helicate [Cu2L12] (1) and related copper(II) complex [CuL2(CH3CN)] [ClO4]2 (2) and silver(I) complexes [AgL2(CH3CN)][BF4] (3) and [AgL2] [BF4](4) have been achieved. These complexes are derived from inexpensive and easy-to-prepare ferrocene-containing bisbidentate Schiff-base ligands H2L1, [(C6H4)(OH)CHNNC(CH3) (C5H4)]2Fe, and L2, [(C5H4N)CHNNC(CH3) (C5H4)]2Fe. The neutral double-helical dicopper(II) complex 1 crystallizes in a polar space group. The two ferrocene-containing ligands strand interwined about each other and around the two tetrahedral copper ions in a double-helical fashion, with the Cu&mellip;Cu separation being 9.45 A . The four metal centers are coplanar and form a slightly distorted rhombus with sides of ca. 5.8 A . Reaction of the ligand L2 and copper(II) constructed a mononuclear copper complex, 2. X-ray structural analysis reveals that the copper(II) atom is coordinated in a distorted square pyramidal geometry, with four nitrogen atoms from the two bidentate bind sites forming the basal plane; the acetonitrile nitrogen atom occupies the apical position. The molecular structure of the silver(I) complex 3 is quite similar to that of copper complex 2, with the silver(I) surprisingly coordinated in a square pyramidal geometry. The silver(I) atom in mononuclear silver complex 4 is coordinated in a new square planar fashion. The result presented here shows that while the ligand (L1)2- can bridge two metal ions to give a double helicate with Cu(II), the ligand L2 acts as a tetradentate ligand chelate to a single metal center in its structurally characterized complexes with Cu(II) and Ag(I). Crystal structures of the free ligand H2L1 and L2 are also reported for comparison.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-94-5

By means of base-catalysed condensation of 1-acyl-/1,1?- diacylferrocenes (acylformyl or acetyl) with 3-formyl- and 3,7- diacetylphenothiazines a series of novel mono- and bis-chalcones were prepared. The enhanced reactivity of the enolate anions of the mono-chalcone intermediates relative to that of the enolates of the corresponding diacetyl-substituted precursor was interpreted by the electron-releasing effect of the ferrocenyl- or phenothiazinyl group present in the beta position of the enone subunit. The structures of the novel products were evidenced by IR, 1H and 13C NMR spectroscopy including 2D-COSY, 2D-HSQC and 2D-HMBC measurements.

A ferrocenyl ligand was prepared from condensation of 1,1?- diacetylferrocene dihydrazone with salicylaldehyde. The ligand forms 1:1 complexes with Pd(II) and Pt(II) in good yield. Characterization of the ligand and complexes was carried out using elemental analysis, infrared study, 1H and 13C nuclear magnetic resonance, and electronic absorption spectra. Anticancer activity of the prepared ligand and its complexes against human breast cancer cell line MCF-7 was determined, and the results were compared with the activity of the commonly used anticancer drug cisplatin. The results suggested that the prepared compounds possess significant antitumor activity comparable to the activity of cisplatin.

Acylferrocenes reacted with samarium diiodide in the presence of water to give the corresponding (alpha-hydroxyalkyl)ferrocenes or alkylferrocenes depending on the reaction time and temperature. On treatment with samarium diiodide in the absence of water, ferrocenecarbaldehyde underwent a reductive coupling to give pinacols, whereas acetylferrocene yielded 3,3-diferrocenyl-2-butanone and 2,3-diferrocenyl-2-butene via the subsequent rearrangement and deoxygenation.

Poly(azine ferrocene-triazole-xanthone amide) (PAFTXA) was successfully synthesized from azine ferrocene bisacetylene (AFcB) and 2,7-(N-2-azidoacetamide) xanthone (NAzX) by using click chemistry protocol. In this paper, innovative AFcB moiety incorporated in this procedure as a monomer. This monomer was prepared in three steps from ferrocene scaffold, and the synthetic processes were discussed in details. Characterization of the synthesized novel intermediate materials, monomer, and the resulting polymer was performed by nuclear magnetic resonance, Fourier transform infrared, thermal gravimetric analysis, differential scanning calorimetry, and ultraviolet-visible spectrophotometer. In addition, the in vitro antibacterial activity of the polymer was appraised against Gram-positive and Gram-negative bacteria by using minimum inhibitory concentration method. Moreover; antitumoral effects of synthesized polymer were evaluated on Hela, MCF-7, and Saos cancer cell lines and compared with normal fibroblast cell line by means of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Promising antiproliferative effects were detected on both epitheloid and mesenchymal cancer cell lines depending on PAFTXA concentration and time. Survey on its characteristic features revealed the proficiencies of our prepared biomaterial such as its high thermal stability as well as valuable antitumoral and antibacterial capabilities that make it an appreciable candidate for further bioapplications.
