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.

Ligand-controlled phosphine-free Co(II)-catalysed cross-coupling of secondary and primary alcohols

Cobalt(II) complexes (5 mol% Co) bearing phosphine-free N?N?N pincer ligands efficiently catalyze C?C coupling of secondary and primary alcohols to selectively form alpha-alkylated ketones with a good functional group compatibility using NaOH (20 mol%) as a base at 120 C. The NH group on the N?N?N?Co(II) precatalyst controls the activity and selectivity. This simple catalytic system is involved in the synthesis of quinolones via the dehydrogenative annulation of 2-aminobenzyl alcohols with secondary alcohols.

Cerium ammonium nitrate: an efficient catalyst for carbon-carbon bond formation from ferrocenyl alcohol substrate

The substitution reaction of ferrocenyl alcohol with various nucleophiles catalyzed by cerium ammonium nitrate (CAN) was investigated. This CAN-mediated direct carbon-carbon bond formation provides the corresponding products in moderate to high yields with relatively lower catalyst loading (5 mol %) at room temperature. It demonstrated a convenient synthetic protocol for the ferrocene functionalities. Crown Copyright

Collisional activation (CA) mass spectrometry has been employed to show that C6H6Fe+ ions formed upon electron impact of dicarbonyl-(eta5-2,4-cyclopentadienyl)-methyliron consist of a 1:1 mixture of fulvene-iron and benzene-iron structures.Analysis of daughter-ion spectra of the deuterium-labelled analogue shows that there exist two independent fragmentation routes leading to the different ion structures.These routes differ in the sequence in the sequence in which the CO ligands and H2 are lost from the molecular ion.

New ferrocene based dithiolate ligands

The preparation and characterization of the three ferrocene based dithiolane complexes [(eta5-C5H5) Fe(eta5-C5H4)NHC(O)(CH2)4CHS 2CH2CH2]1, [(eta5- C5H5)Fe(eta5-C5H 4)CH2OC(O)(CH2)4CHS2CH 2CH2] 2 and [(eta5-C5H 5)Fe(eta5-C5H4)NHC(O)(CH 2)CHS2CH2CH2] 3, with different spacer groups between the ferrocenyl moiety and the dithiolane unit, are reported. The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(0), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)2(S2CH2CH 2CH-kappa2-S,S)(CH2)4C(O) NH(eta5-C5H4)Fe(eta5-C 5H5)] 4 and [Pt(PPh3)2(S 2CH2CH2CH-kappa2-S,S)(CH 2)4C(O)OCH2(eta5-C 5H4)Fe(eta5-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(eta5-C5H5)Fe(eta5- C5H4)NHC(O)(CH2)4CH(SSiMe 3)CH2CH2(SSiMe3)] 7 and [(eta5-C5H5)Fe(eta5-C 5H4)CH2OC(O)(CH2) 4CH(SSiMe3)CH2CH2(SSiMe 3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4.

A reaction between cynichrodenoic acid, (eta5-C5H4COOH)Cr(CO)2NO (6) and phosphorus pentachloride produces cynichrodenoyl chloride (11) in high yield.Subsequent reaction of 11 with sodium azide affords cynichrodenoyl azide (12), which undergoes Curtius rearrangement to form cynichrodenyl isocyanate (13).Subsequent hydrolysis of isocyanate 13 in aqueous KOH solution yields aminocynichrodene (14).Azide 12 also undergoes Curtius rearrangement in the presence of benzyl alcohol to produce benzyl N-cynichrodenylcarbamate (15).Reactions of acid chloride 11 with ammonia, dimethylamine or aniline lead to the corresponding carboxamides (16-18).Amide 16 is readily dehydrated to produce cynichrodenecarbonitrile (19).Reactions of acid chloride 11 with either benzyl alcohol or hydroxymethylferrocene generate the corresponding esters (20-21), whereas treatment of a tetrahydrofuran solution of 11 with pyridine affords cynichrodenecarboxylic anhydride (22) in low yield.Reactions of acetylcynichrodene (2) with organolithium reagents, leading to both carbonyl addtion and condensation products, have been investigated.Treatment of 2 with lithium diisopropylamide in diethyl ether solution produces the self-condensation product 1,3-dicynichrodenyl-but-2-en-1-one (24).Acetyl derivative 2 and benzaldehyde also undergo Claisen-Schmidt condensation in the presence of lithium diisopropylamide to afford cinnamoylcynichrodene (27).

Diiron nonacarbonyl oxidized a series of alpha-phenylcarbinols to their corresponding aldehydes and ketones.In addition, this resagent converted 4-methoxybenzyl alcohol to 4-methoxybenzyl ether, albeit in low yield.Under the same reaction conditions, oxidation was a minor with a group of alpha-ferrocenylcarbinols as ether synthesis was the major reaction with those substrates which could not dehydrate; however, stereoselective olefin synthesis predominated when elimination was possible.
