Synthesis, NMR, IR spectroscopic and X-ray study of novel [pyridazin-3(2H)-one-6-yl]ferrocenes and related ferrocenophane derivatives. Study on ferrocenes. Part 14

On treatment with glyoxylic acid and hydrazine hydrate, 1,1?-diacetylferrocene was converted into the separable mixture of 1,1?-bis [pyridazin-3(2H)-one-6-yl]ferrocene and the hydrazone as well as the azine of 1-acetyl-1?-[pyridazin-3(2H)-one-6-yl]ferrocene. Successful cyclizations of 1,1?-bis[pyridazin-3(2H)-one-6-yl]ferrocene resulting in a series of novel ferrocenophanes containing heterocyclic units were performed under phase transfer- and homogeneous catalytic (RCM) conditions by the application of versatile dialkylating agents and second generation Grubbs’ catalyst, respectively. The structures were determined by mass spectrometry, IR, 1H and 13C NMR spectroscopy including 2D-COSY, HMQC and HMBC measurements. The solid phase structure of a dimer product with pi-stacking interaction was revealed by X-ray analysis.

Ferrocene-tryptophan conjugate: An example of a redox-controlled reversible supramolecular nanofiber network

In this study, the tryptophan derivative of ferrocene-1,1?- dicarboxylic acid self-assembles in toluene to form a supramolecular nanofibrillar network structure. The ferrocene bioconjugate based nanofibers are responsive toward oxidation/reduction and show thermo and redox reversibility. Interestingly, redox-induced reversible morphological transformations between nanofiber and spheroid were observed. The self-assembly was characterized by 1H NMR spectroscopy, FT-IR spectroscopy, UV-vis spectroscopy, circular dichroism (CD), and transmission electron microscopy (TEM).

Input of P, N-(phosphanyl, amino)-ferrocene hybrid derivatives in late transition metals catalysis

Unequally functionalized ferrocenes give access to valuable hemilabile reactivity in catalytic reaction. We address the synthesis of hybrid (P, N)-ferrocenyl compounds for which recent catalytic breakthrough applications have been reported, transversely in late transition metals chemistry. Palladium, nickel, rhodium, iridium, and emerging iron and gold catalysis are illustrated from selected examples, which include C?C bond formation from cross-coupling and polymerization, allylic substitution, cyanation, hydroformylation, C?H arylation and silylation and hydrogenation reactions.

Products of hydrolysis of (ferrocenylmethyl)trimethylammonium iodide: Synthesis of hydroxymethylferrocene and bis(ferrocenylmethyl) ether

The attempted coupling of (ferrocenylmethyl)trimethylammonium iodide (1) with 1,4,7-(triformyl)-1,4,7,10-tetraazacyclododecane (2) in water led to the formation of the expected compound 1-(ferrocenemethyl)-4,7,10-(triformyl)-1,4,7,10-tetraazacyclododecane (3). In addition, hydrolysis of the ferrocenyl precursor 1 led to the formation of two other known compounds, hydroxymethylferrocene (4) and bis(ferrocenylmethyl) ether (5). An X-ray crystal structure determination of 4 revealed the presence of H-bonding between the hydroxyl groups of one molecule of 4 and the oxygen atom of an adjacent molecule resulting in a left-handed helical chain of molecules lying along the b-axis direction. The O?O distances are significantly shorter than those found in previously reported structures of hydroxymethylferrocene derivatives indicative of moderate strength H-bonding interactions. In the structure of 5, the orientation of the ferrocenyl groups are staggered relative to a vector comprising the two carbons of the C-O-C linker. Crown Copyright

Light-controlled switching of the spin state of iron(III)

Controlled switching of the spin state of transition metal ions, particularly of FeII and FeIII, is a prerequisite to achieve selectivity, efficiency, and catalysis in a number of metalloenzymes. Here we report on an iron(III) porphyrin with a photochromic axial ligand which, upon irradiation with two different wavelengths reversibly switches its spin state between low-spin (S = 1/2) and high-spin (S = 5/2) in solution (DMSO-acetone, 2:598). The switching efficiency is 76% at room temperature. The system is neither oxygen nor water sensitive, and no fatigue was observed after more than 1000 switching cycles. Concomitant with the spin-flip is a change in redox potential by ~60 mV. Besides serving as a simple model for the first step of the cytochrome P450 catalytic cycle, the spin switch can be used to switch the spin-lattice relaxation time T1 of the water protons by a factor of 15.

Highly Reactive Manganese(IV)-Oxo Porphyrins Showing Temperature-Dependent Reversed Electronic Effect in C-H Bond Activation Reactions

We report that Mn(IV)-oxo porphyrin complexes, MnIV(O)(TMP) (1) and MnIV(O)(TDCPP) (2), are capable of activating the C-H bonds of hydrocarbons, including unactivated alkanes such as cyclohexane, via an oxygen non-rebound mechanism. Interestingly, 1 with an electron-rich porphyrin is more reactive than 2 with an electron-deficient porphyrin at a high temperature (e.g., 0 C). However, at a low temperature (e.g., -40 C), the reactivity of 1 and 2 is reversed, showing that 2 is more reactive than 1. To the best of our knowledge, the present study reports the first example of highly reactive Mn(IV)-oxo porphyrins and their temperature-dependent reactivity in C-H bond activation reactions.

Binding properties of ferrocene-glutathione conjugates as inhibitors and sensors for glutathione S-transferases

The binding properties of two electroactive glutathione-ferrocene conjugates that consist in glutathione attached to one or both of the cyclopentadienyl rings of ferrocene (GSFc and GSFcSG), to Schistosoma japonica glutathione S-transferase (SjGST) were studied by spectroscopy fluorescence, isothermal titration calorimetry (ITC) and differential pulse voltammetry (DPV). Such ferrocene conjugates resulted to be competitive inhibitors of glutathione S-transferase with an increased binding affinity relative to the natural substrate glutathione (GSH). We found that the conjugate having two glutathione units (GSFcSG) exhibits an affinity for SjGST approximately two orders of magnitude higher than GSH. Furthermore, it shows negative cooperativity with the affinity for the second binding site two orders of magnitude lower than that for the first one. We propose that the reason for such negative cooperativity is steric since, i) the obtained thermodynamic parameters do not indicate profound conformational changes upon GSFcSG binding and ii) docking studies have shown that, when bound, part of the first bound ligand invades the second site due to its large size. In addition, voltammetric measurements show a strong decrease of the peak current upon binding of ferrocene-glutathione conjugates to SjGST and provide very similar K values than those obtained by ITC. Moreover, the sensing ability, expressed by the sensitivity parameter shows that GSFcSG is much more sensitive than GSFc, for the detection of SjGST.

Ferrocenylmethyl-functionalized 5-membered heterocycles: Synthesis, solid-state structure and electrochemical investigations

Treatment of Fe(eta5-C5H4CH2OH)2 (1) with two equivalents of ClC(O)R (2) (a, R = 2-cC4H3O; b, R = 2-cC4H3S; c, R = 2-cC4H3Se; d, R = 3-cC4H3S) produced the corresponding ferrocenylmethyl carboxylates Fe(eta5-C5H4CH2OC(O)R)2 (3a?d), while the reaction of FcCH2OLi (Fc = Fe(eta5-C5H5)(eta5-C5H4)) with 2,5-(ClC(O))2-cC4H2X (5) (a, X = O; b, X = S; c, X = Se) in a 2:1 molar ratio gave 2,5-(FcCH2OC(O))2-cC4H2X (6a?c). Compounds 3a?d and 6a?c were characterized by elemental analysis, NMR (1H and 13C{1H}) and IR spectroscopy. The molecular structures of 3a,b,d in the solid state were determined by single crystal X-ray structure analysis. Compound 3a crystallizes in the monoclinic space group P21/c, while 3b,d crystallize in the triclinic space group P-1¡¥. The ester groups and the heteroatoms are in an anti arrangement with respect to each other. Cyclic voltammetry measurements for 3a?d and 6a?c show reversible electrochemical processes (Fc/Fc+) between 165 and 176 mV for 3a?d, and 94 and 116 mV for 6a?cb, using [NnBu4][B(C6F5)4] as the supporting electrolyte. It was found that for 3a, a somewhat higher Fc/Fc+ redox potential (E0?) is observed when compared with the more electron-rich systems 3b,c,d. The molecular electronic structures of the title compounds were additionally investigated by DFT calculations, revealing different degrees of HOMO?LUMO energy gaps within the series, due to a lowering of the LUMO energy, depending on the nature of the heterocyclic ring.
