Iridium-Catalyzed Cyclization of Isoxazolines and Alkenes: Divergent Access to Pyrrolidines, Pyrroles, and Carbazoles

A heterogeneous iridium-complex-catalyzed N-O-cleaving rearrangement/cyclization of 2,3-dihydroisoxazoles with alkenes has been developed. It provides divergent access to multiple substituted pyrrolidines, pyrroles, and carbazoles. The iridium catalyst remains highly catalytic active after seven cycles. The gram-scale synthesis afforded a carbazole with strong bluish-violet fluorescence.

Dimethylzinc adducts with macrocyclic amines

The structures of dimethylzinc adducts with the macrocyclic amines 1,4,8,1 l-tetramethyl-1,4,8,11-tetraazacyclotetradecane, 1, and 1,4,7,10,13,16-hexamethyl-l,4,7,10,13,16-hexaazacyclooctadecane, 2, have been determined by X-ray diffraction analysis. The adducts each contain two dimethylzinc moieties. In 1 the dimethylzinc moiety forms a six-membered chelate ring with adjacent nitrogen atoms, in preference to the more sterically strained 5-membered ring. In 2 dimethylzinc exists in a 5-membered chelate ring configuration. Compounds 1 and 2 can be used as intermediate adducts in the adduct purification of dimethylzinc for use in the MOCVD of II-VI and III-V materials. The Royal Society of Chemistry 2000.

Influence of surfactants on Fe2O3 nanostructure photoanode

Fe2O3 nanostructures photoanodes were prepared via sol-gel spin-coating method onto fluorine-doped tin oxide glass substrates using six different surfactants: polyethylene glycol (PEG-300), Triton X-100, pluronic F127, cetyltrimethylammonium bromide (CTAB), octadecyltrimethylammonium bromide (OTAB) and tetradecyltrimethylammonium bromide (TTAB). The resulting films have thickness from 520 ¡À 10 to 980 ¡À 10 nm after calcinations at 450C in the air. A comparative study of photocatalytic activity of thin films was performed. The photo-generated samples were determined by measuring the currents and voltages under illumination of UV-vis light. The highest photocurrent density of 1.77 mA/cm2 at 1 V/SCE, under illumination intensity of 100 mW cm-2 from a solar simulator with a global AM 1.5 filter, were produced by TTAB treated sample. The optical properties, morphology, surface roughness and structure of the films were also characterized by UV-visible spectroscopy, SEM, AFM and XRD. The results are consistent with photocatalytic performance: TTAB treated sample has the highest grain size and optical absorption. The improved performance of this sample can be attributed to the crystallinity process of TTAB, which leads to the larger grain size and highest photocatalytic activity. The study demonstrates that photoelectrochemical performance of metal oxide can be improved by simply changing surfactant. The results highlighted the superior performance of cationic surfactants over non-ionic surfactants in preparing Fe 2O3 photoanodes by sol-gel method. Moreover, the study showed that decreasing hydrocarbon tail of cationic surfactants can increase the crystallite size and improve photocatalytic activity. Copyright

Electrolytes, SEI Formation, and Binders: A Review of Nonelectrode Factors for Sodium-Ion Battery Anodes

Through intense effort in recent years, knowledge of Na-ion batteries has been advanced significantly, pertaining to electrodes. Often, such progress has been accompanied by using a convenient choice of electrolyte or binder. Nevertheless, it has been witnessed that ?external? factors to electrodes, such as electrolytes, solid electrolyte interphase, and binders, affect the functions of electrodes profoundly. And generally, certain types of electrodes favor some electrolytes or binders. With a rapidly increasing number of publications in the area, trends in terms of electrolytes and binders are possibly exploitable. Unfortunately, the field has yet to see a review article that devotes itself to these nonelectrode aspects of Na-ion batteries. Here, the gap is filled by conducting a comprehensive review of these nonelectrode external factors, especially by looking into their correlation with electrochemical properties, such as cycle life, and first cycle coulombic efficiency. Not only are the representative reports reviewed, but also quantitative analyses on the database that are constructed are provided. With such analyses, some new data-driven perspectives are postulated, which are of great value to the community.

Metal?Organic Frameworks for Biomedical Applications

Metal?organic frameworks (MOFs) are an interesting and useful class of coordination polymers, constructed from metal ion/cluster nodes and functional organic ligands through coordination bonds, and have attracted extensive research interest during the past decades. Due to the unique features of diverse compositions, facile synthesis, easy surface functionalization, high surface areas, adjustable porosity, and tunable biocompatibility, MOFs have been widely used in hydrogen/methane storage, catalysis, biological imaging and sensing, drug delivery, desalination, gas separation, magnetic and electronic devices, nonlinear optics, water vapor capture, etc. Notably, with the rapid development of synthetic methods and surface functionalization strategies, smart MOF-based nanocomposites with advanced bio-related properties have been designed and fabricated to meet the growing demands of MOF materials for biomedical applications. This work outlines the synthesis and functionalization and the recent advances of MOFs in biomedical fields, including cargo (drugs, nucleic acids, proteins, and dyes) delivery for cancer therapy, bioimaging, antimicrobial, biosensing, and biocatalysis. The prospects and challenges in the field of MOF-based biomedical materials are also discussed.

Synthesis of 4-substituted styrene compounds via palladium-catalyzed suzuki coupling reaction using free phosphine ligand in air

The air-stable and easy to prepare nonsymmetric Schiff base ligands have been synthesized and proven to be efficient ligands for Suzuki cross-coupling reaction between aryl bromides and arylboronic acids using PdCl 2(CH3CN)2 as palladium source under aerobic conditions. The coupling reaction proceeded smoothly using N-[(3,4- dimethoxyphenyl)methylene]-1,2-benzenediamine (L3) as ligand under mild conditions to provide 4-substituted styrene compounds in good yields.

4-exo cyclizations by template catalysis

Small rings through large templates: A two-point binding of the substrate radicals to cationic titanocene templates is essential for the success of otherwise impossible 4-exo cyclizations (see scheme; Bn=benzyl). The cyclobutanes are obtained in high stereoselectivity and can be additionally functionalized in a straightforward manner.

Synthesis of Fe-MFI zeolites in fluoride-containing media

As many as three Fe/u.c. were introduced into the MFI framework in a fluoride-containing medium. Initial gels of the composition x = 0.1, 0.2 and 0.3, and y = 3, 6, 9, 12, 15, 18, 21 and 24, TPABr = tetrapropylammonium bromide) were heated under hydrothermal conditions at 170 C. NH4- and Cs-containing systems are most effective in the incorporation of Fe into the framework. The location of iron on tetrahedral framework positions is indicated by both the white color of the samples and the isomer shift in the Mo?ssbauer spectra (IS < 0.3 mm/s). During calcination, some framework Fe atoms leave the framework. The crystallization patterns and crystal morphologies are influenced by the fluoride salt added to the reaction mixture. Kinetic data show that the cations exert specific forces on the stabilization of the crystals under development.
