A series of new multi-ferrocenyl substituted pyridine derivatives, 4,6-diferrocenyl-3,5-diferrocenylethynyl-2-methylpyridine (1), 3,6-diferrocenyl-4,5-diferrocenylethynyl-2-phenylpyridine (2), 4,6-diferrocenyl-3,5-diferrocenylethynyl-2-phenylpyridine (3), 3,5-diferrocenyl-4,6-diferrocenylethynyl-2-phenylpyridine (4) were synthesized by dicarbonylcyclopentadienylcobalt mediated [2 + 2 + 2] cycloaddition reaction. The molecular composition and structure of compounds 1–4 were characterized by FT-IR, NMR, MS, CV and Elemental analysis. The molecular and crystal structure of compound 1 was determined by X-ray single crystal diffraction analysis.The cyclic voltammetry and square wave voltammetry highlight the electrochemical behaviors of compounds 1–4, which indicates multi-step reversible redox processes of ferrocenyl moieties have occurred. The wave splitting and ΔE1/2 (oxidation potential difference) values of 1–4 were carefully analyzed, which reveals that the interactions between the ferrocenyl units of 1–4 are related to their molecular structures. The molecular structures of isomers 2–4 have been identified by their electrochemical properties and spectroscopic information.Four new multi-ferrocenyl pyridine derivatives were synthesized via [2 + 2 + 2] cycloaddition reaction using Fc–CC–CC–Fc and CH3CN or PhCN as reactants, CpCo(CO)2 as catalyst.

Two novel bimetallic complexes, [Cr(CO)3(η6-C6H5)–C≡C–C6H4–Fc] (Fc = C5H5FeC5H4] (1) and [Cr(CO)3(η6-C6H5)–C ≡ C–Fc–C(CH3)2–Fc] (3), were synthesized by the Sonogashira coupling reaction. By using of (1) and (3) as ligands to react with Co2(CO)8, two others novel polymetallic complexes, [Cr(CO)3(η6-C6H5){Co2(CO)6-η2-μ2-C≡C–}–C6H4–Fc] (2) and [Cr(CO)3(η6-C6H5){Co2(CO)6-η2-μ2-C≡C–}Fc–C(CH3)2–Fc] (4) were obtained. Four carbonyl complexes were characterized by elemental analysis, FT-IR, NMR and MS. The molecular structures of complexes (1), (2) and (4) were determined by single crystal X-ray diffraction. The interactions among the ferrocenyl, Cr(CO)3 and Co2(CO)6-η2-μ2-C≡C– units were investigated by cyclic voltammetry.

Abstract

Chelerythrine was successfully micronized from methanol solution using Supercritical Carbon Dioxide (SC-CO₂) as an antisolvent via the Solution Enhanced Dispersion by Supercritical Fluids through the Prefilming Atomization (SEDS-PA) process. The morphology and particle size of the chelerythrine microparticles were visually analyzed by scanning electron microscopy (SEM). For the purpose of the optimizing operating conditions of the SEDS-PA process, the influences of the experimental variables, i.e., temperature, pressure, solution flow rate and initial solution concentration, on the particle size and morphology of chelerythrine microparticles are discussed in detail. The results show that the best process conditions for the micronization of chelerythrine are: T = 313 K, P = 20 MPa, C = 2.0 g/L and F = 2.0 mL/min. The precipitates obtained under the optimized experimental conditions are short rod-like chelerythrine microparticles with a mean particle size of 0.1–1 μm in width.

Abstract

The micronization of emodin in a mixed solution of dichloromethane and methanol by the Solution Enhanced Dispersion by Supercritical Fluids through Prefilming Atomization (SEDS-PA) process has been successfully performed. Morphologies and particle sizes (PSs) of the emodin microparticles were analyzed by scanning electron microscopy. The results of micronization show that the acicular or rod-like emodin crystals with PSs of about 3-10 µm wide and 100-300 µm long have successfully been micronized to needle-like, rod-like, twisted fiber-like and coalesced net-like microparticles with PSs of about 0.1-1.0μm wide and 2-40μm long by the SEDS-PA process. The effect of technological conditions on micronization has been studied. With the increase of initial solution concentration and temperature, the PSs of emodin microparticles increase. With the increase of solution flow rate and pressure, the PSs of emodin microparticles decrease. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
