The synthesis and characterization of a family of air-stable primary, secondary, and tertiary phosphines containing all possible combinations of ethylferrocene and ethylruthenocene substituents are reported. Each phosphine was characterized by 1H, 13C, and 31P NMR spectroscopy, IR and UV-vis absorption spectroscopy, mass spectrometry, and elemental analysis. With the exception of primary ethylruthenocene phosphine 8a, all of the title compounds have been studied by single-crystal X-ray crystallography. Ferrocene-containing phosphines showed maximum absorption at wavelengths of ca. 440 nm and qualitatively reversible oxidation waves in their cyclic voltammograms with intensities scaling to the number of ferrocene units present. The average metal-cyclopentadienyl centroid distances observed for ferrocene-containing phosphines were shorter than those of ruthenocene-containing phosphines, which also had maximum absorption wavelengths of ca. 320 nm and underwent irreversible electrochemical oxidation. Phosphines containing both ethylferrocene and ethylruthenocene substituents displayed properties consistent with the presence of both metallocene types.

The first organometallic derivatives of tricyclic quinazoline derivatives are prepared by condensation of the active C-3 methylene group of 7H-deoxyvasicinones with ferrocenecarbaldehyde. By following this route the conjugated parent alkaloid and derivatives with nitro, amino, as well as some alkanoylamino groups at C-7 were attached at the ferrocene moiety, thereby significantly extending the pi system. In addition, the parent compound was subjected to the reaction by treatment with ferrocene-1,1?-dicarbaldehyde, giving rise to the double condensation product, which is only the second case of a 1,1?-disubstituted ferrocene derivative with two alkaloid substituents. A number of the compounds obtained were subjected to X-ray crystallographic analyses. In all cases, the substituents adopt a coplanar conformation with the ferrocene cyclopentadienyl ligands. The influence of the substituents at C-7 through the extended conjugated pi system on the iron atom is reflected by results of cyclic voltammetric measurements as well as by DFT calculations. 7H-Deoxyvasicinones are condensed with ferrocenecarbaldehyde and with ferrocene-1,1?-dicarbaldehyde to generate extended pi systems with coplanar conformations of the two moieties. The products are investigated by crystal structure analyses, cyclic voltammetry, and DFT calculations.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

Introducing a new discovery about 1273-86-5, Name is Ferrocenemethanol

Three novel monomers based on carbazole-3, 4-ethoxylenedioxythiophene and redox groups were synthesized and characterized. Their polymer films were obtained by electropolymerization. Cyclic voltammetry and spectroelectrochemistry of the polymer films showed that they possessed multi-electrochromic property. The presence of ferrocene and 2,2,6,6-tetramethyl-1-piperidinyloxy units not only changed the films? colour but also improved their switching time due to their excellent electrochemical properties. Additionally, the polymer films also possessed a reasonable transmittance change, which made them promising candidates for use in electrochromic devices.

Mono and doubly alkynyl substituted ferrocene complexes, [Fc(CH2OCH2C{triple bond, long}CH)n], 2-3 (2: n = 1; 3: n = 2; Fc = ferrocene) have been synthesized from the room temperature reaction of mono and 1,1?-dihydroxymethyl ferrocene, Fc(CH2OH)n, 1a-b (1a: n = 1; 1b: n = 2) and propargyl bromide, in modest to good yields. These new ferrocene derivatives have been characterized by mass, IR, 1H, 13C NMR spectroscopy, and molecular structures of compound 2 and 3 were unequivocally established by single crystal X-ray diffraction study. The crystal structure analysis revealed that 2 and 3 consist of infinite 1D zig-zag hydrogen bonded chains and 2D microporous hydrogen bonded network of molecules, linked by intermolecular C-H···O hydrogen bonding. The molecular structures of both 2 and 3 are further stabilized by C-H···pi interactions.

Having gained chemical understanding at molecular level, Computed Properties of C11H3FeO, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. In a patent，Which mentioned a new discovery about 1273-86-5

Comparative analysis of the specific features of autooxidation of ferrocenylacetic acid (FcCH2COOH) in organic solvents at 30-50C in the absence and in the presence of trifluoroacetic acid (processes 1 and 2 respectively) was carried out. It was shown that both reactions proceed as a sequence of two macrostages, the molecular and the chain radical oxidation of the metal complex. Introduction of acid (HX) in the reaction mixture leads to a significant increase in the rate of the process, in the amount of oxygen per one mole of metal complex absorbed by the reaction mixture, and to the change in the yields of main reaction products like hydroxymethylferrocene, formylferrocene, ferrocenylpyruvic acid, and CO2. On the basis of results of the investigation performed, the kinetic and thermodynamic analysis of primary reactions of the process probable mechanisms of both macrostages in both processes were suggested. The significant effect of approach and orientation on the rate of the molecular oxidation of complex as the bifunctional reagent was noted. An assumption was made that the acid takes place in the molecular oxidation of FcCH2COOH according to two alternative mechanisms differing by the way of its coordination with O2 and the metal complex in the prereactional intermediates. The oxidative transformation of these intermediates leads to the generation of radicals of different nature, Fc+?CH2C(O)OO? and HO 2 ? which initiate the chain radical oxidation of the metal complex.

From the reaction of [PtCl2(N-CMe)2] with FcC-N (1) (Fc = Fe(eta5-C5H4)(eta5-C 5H5)) complex [PtCl2(FcC-N)(N-CMe)] (2) was obtained, which on subsequent treatment with 1 gave trans-[PtCl 2(N-CFc)2] (trans-3). The latter complex and the appropriate cis isomer (cis-3) were also accessible when [PtCl2] or [PtCl2(N-CMe)2] is reacted with a 2.6-fold excess of 1. Appropriate treatment of [PtCl2(N-CMe)2] with two equivalents of 1-acetyl-1′-cyanoferrocene (4) produced trans-[PtCl 2(Fe(eta5-C5H4CN)( eta5-C5H4C(O)Me))2] (trans-5). Coordination polymer [PtCl2(Fe(eta5-C5H 4CN)2)]n (7) was obtained by combining [PtCl2(N-CPh)2] with [Fe(eta5-C 5H4CN)2] (6). However, when 7 was reacted with PPh3 for deaggregation, [PtCl2(PPh3) 2] was formed. Addition of FcC-CLi (8-Li) to trans-3 gave pentametallic trans-[Pt(C-CFc)2(NH-CnBuFc)2] (10) via trans-[Pt(C-CFc)2(N-CFc)2] (9). When trans-3 is reacted with two equivalents of nBuLi in the absence of FcC-CH (8), trans-[PtCl2(NH-CnBuFc)2] (11) was obtained, which decomposed to FcC(-NH)nBu (12), giving FcC(O)nBu (13). Electrochemical measurements of the nitrile platinum complexes show no redox separation for the oxidation of the Fc and Fe(eta5-C 5H4)2 moieties. Compared with the noncoordinated ferrocenecarbonitriles, a shift to higher potentials is observed. In contrast, for 10 four well-separated redox events (-185, -90, +460, +545 mV) were found, which could be assigned to the oxidation of the Fc units. UV-vis/NIR spectroscopy allowed to determine an IVCT absorption (numax = 6495 cm-1, epsilonmax = 270 L·mol-1·cm-1, Deltanu1/2 = 2270 cm-1) for 10+, classifying this mixed-valent species as a weakly coupled class II system according to Robin and Day, while no IVCT transitions were observed for 10n+ (n = 2, 3). The structures of trans-3, cis-3, 10, and FcC(O)tBu (15) in the solid state were determined by single-crystal X-ray diffraction. Although the bond distances and angles of trans-3 and cis-3 are similar, the cis isomer crystallizes as a dimer possessing Pt-Pt distances within the sum of the van der Waals radii.

Chemistry involves the study of all things chemical – chemical processes, SDS of cas: 1271-51-8, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. In a patent，Which mentioned a new discovery about 1271-51-8

The dimesitylphosphinocyclopentene/HB(C6F5)2-derived vicinal trans-1,2-P/B frustrated Lewis pair (FLP) 4 shows no direct phosphane?borane interaction. Toward some reagents it behaves similar to an intermolecular FLP; it cleaves dihydrogen, deprotonates terminal alkynes, and adds to organic carbonyl compounds including CO2. It shows typical intramolecular FLP reaction modes (cooperative 1,1-additions) to mesityl azide, to carbon monoxide, and to NO. The latter reaction yields a persistent P/B FLPNO nitroxide radical, which undergoes H-atom abstraction reactions. The FLP 4 serves as a template for the CO reduction by [HB(C6F5)2] to generate a FLP-eta2-formylborane. The formylborane moiety is removed from the FLP template by reaction with pyridine to yield a genuine pyridine stabilized formylborane that undergoes characteristic borane carbaldehyde reactions (Wittig olefination, imine formation). Most new products were characterized by X-ray diffraction.
