Efficient synthesis of ferrocenylquinolines via the friedlaender reaction

Acylferrocenes 2a-c reacted with ortho-aminoarylaldehydes 1a-e via the Friedlnder condensation reaction to afford the corresponding ferrocenylquinolines 3a-o in moderate yields in the presence of sodium ethoxide (30mmol%) under mild reaction conditions. Under the same reaction conditions, 1,1-diacetylferrocene 2d and 1,1-dipropionylferrocene 2e reacted with ortho-aminoaldehydes 1a-e to afford the corresponding 1,1-bis(substituted quinolin-2-yl)ferrocene derivatives 3p-t. The structures of compounds 3a-t were determined and characterized by infrared, 1H NMR, mass spectrometry, and elemental analysis. The crystal structures of 3e and 3q were determined by X-ray crystallography.

Preparation of ferrocenyl mono- and dienone derivatives through aldol condensation of 1,1?-diacetylferrocene with aromatic aldehydes in dry conditions

1,1?-Diacetylferrocene was condensed with aromatic aldehydes without solvent in the presence of solid NaOH. Diacetylferrocene can give good yields of mono- or diene with either one or two molecules of a wide range of aldehydes depending only on the stoichiometry. Cyclization to ferrocenphane does not occur in this condition.

Direct or catalytic condensation of diacylferrocenes (acyl = formyl, acetyl, and benzoyl) and anilines or benzylamines with titanium tetrachloride as a catalyst resulted in the corresponding diimines 1-3, respectively. Reduction of these imines with sodium borohydride or lithium aluminum hydride/aluminum chloride in THF yielded 1,1?-bis[(N-phenyl)aminomethyl(ethyl)]ferrocenes (4, 5) and 1,1?-bis[(N-benzyl)aminobenzyl]ferrocenes (6), respectively. Reductive methylation of 4-6 with aqueous formaldehyde, cyanoborohydride and acetic acid only afforded 1,1?-bis[(N-methyl-N-phenyl)aminomethyl(ethyl)]ferrocenes (7, 8). 1,1?-Bis[{(N-methyl-N-benzyl)amino}benzyl]ferrocenes (9) were not obtained, probably due to their debenzylation under the acidic conditions.

Oxo/Imido heterometathesis reactions catalyzed by a silica-supported tantalum imido complex

Grafting Ta(=NtBu)(CH2CMe2Ph)3 onto the surface of silica partially dehydroxylated at 300C leads to the formation of the surface imido complex (?SiO)2Ta(=N tBu)(CH2CMe2Ph) as a major species, which was characterized with EXAFS, 13C CP/MAS NMR, diffuse reflectance FTIR, elemental analyses, and chemical reactivity. The obtained material acts as an efficient heterogeneous catalyst for various oxo/imido heterometathesis transformations: imidation of ketones and DMF with N-sulfinylamines and condensation of N-sulfinylamines into sulfurdiimines and phenyl isocyanate into diphenylcarbodiimide.

Bonding modes, structures and fluxionality in rhodium and iridium tris(3,5-dimethylpyrazolyl)methane diene complexes

The structures adopted by a range of hydrotris(3,5-dimethylpyrazolyl) methane complexes [ML2{HC(pz?)3}]+ (M = Rh, Ir; L2 = diene) have been investigated. There is low steric hindrance between ligands in [Rh(eta-nbd){HC(pz?)3}] + (nbd = norbornadiene) and [Rh(eta-dmbd){HC(pz?) 3}]+ (dmbd = 2,3-dimethylbuta-1,3-diene) resulting in kappa3 co-ordination of the pyrazolylmethane. The complexes [M(eta-cod){HC(pz?)3}]+ (cod = cycloocta-1,5-diene) (M = Rh, Ir) are kappa2 co-ordinated with the free pyrazolyl ring positioned above and approximately parallel to the square plane about rhodium or iridium. The HC(pz?)3 complexes undergo fast exchange of the co-ordinated and unco-ordinated pyrazolyl rings on the NMR spectroscopic timescale. However, for [Rh(eta-dmbd){HC(pz?) 3}]+, the fluxional process is slowed at low temperatures, so that inequivalent pyrazolyl rings may be observed. A mechanism for the fluxional process is proposed involving dynamic interconversion between isomeric forms in solution. The bonding mode of the HC(pz?)3 ligand can be determined by 13C NMR spectroscopy. The 13C chemical shifts (for the sp3 hybridised carbon of the ligand) show the general pattern, kappa3 < 71.5 ppm < kappa2. The electrochemical behaviour of the pyrazolylmethane complexes is related to the degree of structural change, which occurs on electron transfer and is compared with that of the pyrazolylborate analogues. Bonding modes, structures and fluxionality in rhodium and iridium tris(3,5-dimethylpyrazolyl)methane diene complexes We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1273-94-5, and how the biochemistry of the body works.Computed Properties of C14H6FeO2

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).

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.

Trimethylchlorosilane-modified Clemmensen reduction of metallocenyl ketones: Trapping and X-ray structures of aliphatic, olefinic, silylated pinacolic, and rearranged pinacolonic products

The Clemmensen reduction of a carbonyl group to give, in the simplest cases, a methylene unit, is one of the more familiar reactions in organic chemistry. Trimethylchlorosilane as a replacement for the proton allows controlled reductive deoxygenation of carbonyl compounds under formally anhydrous conditions as an alternative to the McMurry dicarbonyl coupling reaction. Aromatic carbonyl compounds with electron-donor substituents are preferred substrates for this reaction to yield symmetrical olefins in good yield. The high donor capacity of metallocenyl groups should especially favor the clean formation of olefins from the corresponding metallocenyl ketones. In this study, a number of ferrocenyl and ruthenocenyl aldehydes and ketones were treated with Zn and trimethylchlorosilane under controlled anhydrous reaction conditions with (a) catalytical and (b) low amounts of H+ present. The observed main products include alkanes, alkenes, silylated pinacols, and rearranged pinacolones, which have been characterized by spectroscopic methods and by X-ray analyses. The diverse outcome in these reactions indicates a reaction mechanism which involves electrophilic catalysis with different energetically similar pathways.
