New ferrocenyl compounds substituted by sulfur containing groups were synthesized leading to ferrocenyl-3H-1,2-dithiole-3-thiones and related compounds. The substituent of the ferrocene was a [3-thioxo-3H-1,2-dithiol]-4 or 5-yl, a [3-oxo-3H-1,2-dithiol]-4 or 5- yl or a [3-methylsulfanyl-3H-1,2-dithiolium]-4 or 5-yl cation group. Their anodic behavior was studied by cyclic voltammetry at a Pt electrode in aprotic solvent. All synthesized ferrocenes exhibited a one-electron reversible oxidation leading to the corresponding ferricinium cation. At low potential scan, the irreversible oxidation of 5-ferrocenyl-3H-1,2-dithiole-3-thione was observed and attributed to a dimerization involving the dithiolethione group. Redox potential of the reversible oxidation allowed the determination of the electronic effect of the 1,2-dithiole groups. The Hammett sigmap constants of the dithiole substituents were obtained from linear correlation between oxidation potentials and electronic effects. The results showed that the [3-thioxo-3H-1,2-dithiol]-5-yl and the [3-methylsulfanyl-3H-1,2-dithiolium]-5-yl cation groups were strong inductive electron withdrawing substituents characterized by sigmap values of 0.55 and 0.97, respectively.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-94-5, and how the biochemistry of the body works.COA of Formula: C14H6FeO2

A mononuclear non-heme Mn(III)-aqua complex, [(dpaq)MnIII(OH2)]2+ (1, dpaq = 2-[bis(pyridin-2-ylmethyl)]amino-N-quinolin-8-yl-acetamidate), is capable of conducting hydrogen atom transfer (HAT) reactions much more efficiently than the corresponding Mn(III)-hydroxo complex, [(dpaq)MnIII(OH)]+ (2); the high reactivity of 1 results from the positive one-electron reduction potential of 1 (Ered vs SCE = 1.03 V), compared to that of 2 (Ered vs SCE = -0.1 V). The HAT mechanism of 1 varies between electron transfer followed by proton transfer and one-step concerted proton-coupled electron transfer, depending on the one-electron oxidation potentials of substrates. To the best of our knowledge, this is the first example showing that metal(III)-aqua complex can be an effective H-atom abstraction reagent.

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 reaction of the hydrazones of mono-and 1,1?-diacetylferrocene with mono-and diketones a series of ferrocenylazines has been prepared. The crystal structures of the monobridged ferrocenophane [4](1)(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (II) and of the dibridged ferrocenophane [42](1,1?)bis-(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (VII) have been determined. II exists as a centrosymmetric molecule with eclipsed cyclopentadienyl rings and a planar MeC=NN=CMe bridge whereas VII has staggered cyclopentadienyl rings and non-planar bridges. In II and VII the bridges are in the E,E configuration. The electrochemical results show that the ferrocenium ions of the acetylferrocene and the azines are stable in solution whereas those of the hydrazones are unstable. In agreement with a slightly increasing electronic communication between the two ferrocene units, II undergoes two almost overlapping one-electron oxidations (DeltaE? = 0.09 V) whereas VII displays two more widely separated one-electron oxidations (DeltaE? = 0.12 V).

The enantiomerically pure dibromoferrocene 3 [(Sp,S p)-1,1?-dibromo-2,2?-di(isopropyl)ferrocene], equipped with two iPr groups in alpha positions, was prepared using known “Ugi amine” chemistry. Species 3 was targeted in order to gain access to new [1]ferrocenophanes ([1]FCPs) to be used as monomers for ring-opening polymerization. The iPr groups on the sandwich unit were introduced to stabilize bridging moieties, as well as to increase solubilities of targeted metallopolymers. The planar chiral dibromide 3 can quantitatively be lithiated at 0 C [2 equiv nBuLi, hexanes/thf (9:1), 30 min]. Salt-metathesis reactions with respective element dichloride species gave chiral [1]FCPs with a variety of bridging moieties [ERx=Ga[2-(Me2NCH 2)C6H4] (4 a), SiMe2 (4 b), SntBu2 (4 c), BNiPr2 (4 d)]. The new [1]FCPs were fully characterized including single-crystal X-ray analysis. The stabilizing iPr groups on the Cp rings increase the thermal stabilities of 4 b-d compared to known [1]FCPs, equipped with the same bridging moieties. All three compounds 4 b-d are volatile and could be isolated by vacuum sublimation. Our new approach to [1]FCPs has the potential to overcome many of the existing difficulties in ferrocenophane chemistry, such as limited stability of starting monomers and low solubilities of resulting polyferrocenes. Closing the gap: The preparation of [1]ferrocenophanes with a variety of bridging elements was accomplished by using chiral ferrocene derivatives (see scheme). The isopropyl groups on the sandwich unit serve as protective and solubilizing moieties. The new synthetic approach is superior to the common synthesis of [1]ferrocenophanes, when dilithioferrocene-tmeda is used as the starting material. Copyright

Treatment of 1,1?-diacetylferrocene (4) with dimethylamine and TiCl4 yielded the unsaturated dimethylamino-substituted [3]ferrocenophane product 5. Its catalytic hydrogenation gave the corresponding saturated [3]ferrocenophane system 6 (trans/cis ? 7:1). The rac-[3]ferrocenophane amine 6 was partially resolved (to ca. 80% ee) by means of L- or D-O,O?-dibenzoyltartrate salt formation. Treatment of 4 with the pure (R)- or (S)-methyl(1-phenylethyl)amine (8)/TiCl4 gave the corresponding optically active unsaturated [3]ferrocenophane amines (R)-(+)-9 and (S)-(-)-9, respectively. Their catalytic hydrogenation again proceeded trans-selectively, giving the corresponding saturated diastereomeric [3]ferrocenophane amines (1R,3R,5R)-10a and (1S,3S,5R)-10b [starting from (R)-9], their enantiomers ent-10a and ent-10b were obtained from (S)-9, but with a poor asymmetric induction (10a/10b < 2:1). Quaternization of 6 (CH3I) followed by amine exchange using (R)- or (S)-methyl(1-phenylethyl)amine (8), respectively, proceeded with overall retention. Subsequent chromatographic separation gave the pure diastereoisomers (1R,3R,5R)-10a and (1S,3S,5R)-10b [from (R)-8, ent-10a and ent-10b from (S)-8] in > 60% yield. Subsequently, the benzylic (1-phenylethyl) auxiliary was removed from the nitrogen atom by catalytic hydrogenolysis to yield the enantiomerically pure (> 98%) ([3]ferrocenophanyl)methylamines (1R,3R)-11 and (1S,3S)-11, respectively, which were converted into the corresponding dimethylamino-substituted [3]ferrocenophanes (1R,3R)-6 and (1S,3S)-6. Each enantiomer from the following enantiomeric pairs was isolated in its pure form and characterized by X-ray diffraction: (R)-9/(S)-9; (1R,3R,5R)-10a/(1S,3S,5S)-10a; (1R,3R,5S)-10b/(1S,3S,5R)-10b; (1R,3R)-11/(1S,3S)-11.

A SYMMETRIC 1,1′-disubstituted ferrocene- derived Schiff-bases have been prepared and used as ligands in the preparation of their novel Pd(II) and Pt(IV) metal chelates. The synthesized ligands and their metal chelates have been characterized by their physical, analytical and spectral data. These have also been used for screening against B. subtilis, S. aureus, E. coli, S. typhi (bacteria), C. albicans (yeast), A. niger and F. solani (fungi). The antimicrobial results indicated that the complexes prepared are more active than the ligand and have been found to be a novel class of organometallic-based antimicrobials.
