Physicochemical properties of nitrogen-doped carbon nanotubes from metallocenes and ferrocenyl imidazolium compounds

Shaped carbon nanomaterials (SCNMs) were synthesized via the chemical vapour deposition (CVD) technique by using typical metallocenes (ferrocene, nickelocene, cobaltocene, and ruthenocene), and more interestingly, by use of novel ferrocenyl imidazolium derivatives, containing -Cl (FcImCl), -NO2 (FcImNO2) and -CH3 (FcImCH3) substituents as catalysts. Acetonitrile was applied both as a carbon and nitrogen source at temperatures 800?900 C. The SCNMs, namely, carbon nanotubes (CNTs), carbon spheres (CS), carbon fibres (CF) and amorphous carbons (ACs) were obtained in varying ratios depending on the catalyst and carbon sources. The ferrocenyl imidazolium catalysts produced nitrogen-doped CNTs (N-CNTs) with bamboo-like structures. The yields of various reactions were temperature-dependent, with the highest amount of N-CNTs obtained at 850 C. In all samples, the composition was mainly of CS and N-CNTs except for nickelocene at 800 C that gave CFs as a ?minor? product. Ferrocene and nickelocene in acetonitrile produced well-aligned N-CNTs while cobaltocene and ruthenocene gave ‘spaghetti-like? structures. In the case of ferrocenyl imidazolium catalyst, a coiled N-CNTs morphology was produced from FcImCl catalyst. Also, higher percentage of N-CNTs with traces of CS were obtained from the FcImCl and FcImCH3 catalysts in acetonitrile at 850 C, while higher percentage of CS and AC were obtained for FcImNO2 catalyst. In all the catalysts, the use of acetonitrile promoted nitrogen-doping (samples with more disordered and with smaller outer-diameters). Thus, this study demonstrates that the synthesis of N-CNTs from nitrogen-containing ferrocenyl imidazolium compounds as catalyst sources, provided higher percentage of N-CNTs which can be suitable for various application.

Redox routes to arenechromium complexes of two-, three- and four-electron alkynes: Structure and bonding in paramagnetic [Cr(CO)L(eta-RC?CR)(eta-arene)]+

X-Ray structural studies on the redox pair [Cr(CO)2(eta-PhC?CPh)(eta-C6Me5H)] z (z = 0 and 1) show that one-electron oxidation of the neutral complex results in a shortening of the Cr-Calkyne bonds and a lengthening of the Cr-C(O) bonds, consistent with depopulation of a HOMO antibonding with respect to the metal-alkyne interaction. Oxidation leads to an increase in the substitutional lability of the Cr-CO bonds so that [Cr(CO)2-(eta-RC?CR)(eta-C6Me6)] + (R = Ph or C6H4OMe-p) reacts with Lewis bases to give [Cr(CO)L(eta-RC?CR)(eta-C6Me6)]+ {L = CNXyl, P(OMe)3 and P(OCH2)3CEt}, X-ray studies on which show a rotation of the alkyne to align with the remaining Cr-CO bond. ESR spectroscopic studies on [Cr(CO)L(eta-RC?CR)(eta-C6Me6)]+ show delocalisation of the unpaired electron onto the alkyne ligand, consistent with its description as a three-electron donor. The cations [Cr(CO)L(eta-RC?CR)(eta-C6Me6)]+ undergo both one-electron reduction and oxidation, and chemical oxidation of [Cr(CO){P(OCH2)3CEt} (eta-p-MeOC6H4C?CC6H4OMe-p)( eta-C6Me6)]+ with AgPF6 gives the dication [Cr(CO){P(OCH2)3CEt}(eta-p-MeOC6H4 C?CC6H4OMe-p)(eta-C6Me6)] 2+. Thus the two-electron alkyne of [Cr(CO)2-(eta-RC?CR)(eta-C6Me6)] is converted into the four-electron alkyne of [Cr(CO)L(eta-RC?CR)(eta-C6Me6)]2+ by an ECE (E = electrochemical, C = chemical) process in which all of the intermediates have been fully characterised.

Synthetic Model Complex of the Key Intermediate in Cytochrome P450 Nitric Oxide Reductase

Fungal denitrification plays a crucial role in the nitrogen cycle and contributes to the total N2O emission from agricultural soils. Here, cytochrome P450 NO reductase (P450nor) reduces two NO to N2O using a single heme site. Despite much research, the exact nature of the critical “Intermediate I” responsible for the key N-N coupling step in P450nor is unknown. This species likely corresponds to a Fe-NHOH-type intermediate with an unknown electronic structure. Here we report a new strategy to generate a model system for this intermediate, starting from the iron(III) methylhydroxylamide complex [Fe(3,5-Me-BAFP)(NHOMe)] (1), which was fully characterized by 1H NMR, UV-vis, electron paramagnetic resonance, and vibrational spectroscopy (rRaman and NRVS). Our data show that 1 is a high-spin ferric complex with an N-bound hydroxylamide ligand that is strongly coordinated (Fe-N distance, 1.918 A Fe-NHOMe stretch, 558 cm-1). Simple one-electron oxidation of 1 at -80 C then cleanly generates the first model system for Intermediate I, [Fe(3,5-Me-BAFP)(NHOMe)]+ (1+). UV-vis, resonance Raman, and Moessbauer spectroscopies, in comparison to the chloro analogue [Fe(3,5-Me-BAFP)(Cl)]+, demonstrate that 1+ is best described as an FeIII-(NHOMe)? complex with a bound NHOMe radical. Further reactivity studies show that 1+ is highly reactive toward NO, a reaction that likely proceeds via N-N bond formation, following a radical-radical-type coupling mechanism. Our results therefore provide experimental evidence, for the first time, that an FeIII-(NHOMe)? electronic structure is indeed a reasonable electronic description for Intermediate I and that this electronic structure is advantageous for P450nor catalysis because it can greatly facilitate N-N bond formation and, ultimately, N2O generation.

Three-Component Ruthenium-Catalyzed Direct Meta-Selective C-H Activation of Arenes: A New Approach to the Alkylarylation of Alkenes

Multicomponent reactions are fundamentally different from two-component reactions, as multicomponent reactions can enable the efficient and step-economical construction of complex molecular scaffolds from simple precursors. Here, an unprecedented three-component direct C-H addition was achieved in the challenging meta-selective fashion. Fluoroalkyl halides and a wide range of alkenes, including vinylarenes, unactivated alkenes, and internal alkenes, were employed as the coupling partners of arenes in this strategy. The detailed mechanism presented is supported by kinetic isotope studies, radical clock experiments, and density functional theory calculations. Moreover, this strategy provided access to various fluoride-containing bioactive 1,1-diarylalkanes and other challenging synthetically potential products.

Use of the flux ratio method for mechanistic diagnosis in electroactive polymer film redox switching

The redox switching of poly(vinylferrocene) (PVF) films was investigated using the electrochemical quartz crystal microbalance in conjunction with cyclic voltammetry (at different voltage scan rates) and reverse potential steps. The mechanism of the redox process was determined using PVF films supported on Au electrodes and exposed to aqueous bathing solutions of 0.1 M sodium hexafluorophosphate. PVF electro-oxidation proceeds via coupled oxidation of uncharged ferrocene sites and entry of counterion and is followed by the entry of water into the film. Structural changes within the polymer may also accompany the latter two steps. Any of these three steps may be the slowest for particular redox conditions. The controlling kinetic step depends on the film’s instantaneous water content, its instantaneous oxidation state, the electrochemical control function, the direction of redox switching, and the associated time scale of the experiment. We describe a new general quantitative approach based upon comparison of the instantaneous fluxes of solvent (water) and counterion during the redox cycle to characterize the rate-controlling process as a function of the extent of film oxidation. This new methodology has the capability to resolve time scale- and potential- (charge-) dependent mechanistic shifts and film relaxation phenomena as they are reflected through the ratio of fluxes of solvent and counterions.
