Heterogeneous palladium catalyst constructed with cross-linked hyperbranched poly(phenylacetylene) as polymer support: A reusable highly active ppm-level catalyst for multiple cross-coupling reactions

We demonstrate in this work a unique strategy for the synthesis of heterogeneous Pd catalysts with the use of a hyperbranched poly(phenylacetylene) containing pendant alkyne groups as the cross-linkable polymer substrate. It utilizes the dual functions of Pd-based catalysts in catalyzing both alkyne polymerization/oligomerization and coupling reactions. In the synthesis, a homogeneous Pd(II) catalyst catalyzes the cross-linking of the hyperbranched polymer and simultaneously encapsulates itself into the crosslinked polymer matrix, rendering the heterogeneous catalyst at high yield and high percentage of Pd encapsulation. Three homogeneous catalysts having different ligands (triphenylphosphine, a diphosphine ligand, and a diimine ligand) have been examined for the cross-linking encapsulation and the resulting heterogeneous catalysts have been evaluated for their catalytic performance in coupling reactions. Among the various heterogeneous catalysts obtained, a triphenylphosphine-ligated catalyst, HBPPA-Pd-2, appears to be the optimum one. It shows high activity in catalyzing the Suzuki-Miyaura reactions, the Mizoroki-Heck reactions, and the allylic arylation reactions under air with the Pd loading at as low as mol ppm or even mol ppb levels relative to the reactants. Meanwhile, it facilitates the Suzuki-Miyaura reactions of challenging less reactive aryl chlorides/heteroaryl bromides and the Mizoroki-Heck reactions of aryl bromides as reactants. In addition, it behaves truly as a heterogeneous catalyst with high reusability and low catalyst leaching during the reactions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about Formula: C3H5NO2!, 5394-13-8

Green halogenation of aromatic heterocycles using ammonium halide and hydrogen peroxide in acetic acid solvent

The green generation of X+ (X = Br, I) using hydrogen peroxide in aqueous acetic acid allows access to aromatic heterocyclic halides in yields and purities comparable to syntheses employing N-bromosuccinimide. In activated and unsubstituted thiophene rings, regioselectivity is quantitative for positions alpha to the sulfur; pyrroles also give quantitative reactions, at least initially. Deactivated rings, including furans and thiazoles, as well as thiophenes with strongly electron-withdrawing groups showed little to no reactivity under the conditions investigated. The reaction shows remarkable functional group tolerance (to alcohol, nitro, alkyl, halo, and carbonyl groups), as shown through reaction with substituted phenols. In all bromination reactions, reaction yields and regiochemistry were very similar to reactions involving N-bromosuccinimide in tetrahydrofuran solvent.

A convenient synthesis of 3,4-diaryl(hetaryl)-substituted maleimides and maleic anhydrides

A convenient procedure has been developed for the synthesis of 3,4-diaryl(or hetaryl)maleimides by cross coupling of N-substituted 3,4-dibromomaleimides with aryl(hetaryl)boronic acids in the presence of Pd(Ph3P)4 and CsF. The reaction ensures high yields of the products and requires relatively small amount of the catalyst; it can be performed on an enlarged scale. The resulting maleimides are readily converted into the corresponding maleic anhydrides.

Nickel-catalyzed monoarylation of ammonia

Structurally diverse (hetero)aryl chloride, bromide, and tosylate electrophiles were employed in the Ni-catalyzed monoarylation of ammonia, including chemoselective transformations. The employed JosiPhos/[Ni(cod)2] catalyst system enables the use of commercially available stock solutions of ammonia, or the use of ammonia gas in these reactions, thereby demonstrating the versatility and potential scalability of the reported protocol. Proof-of-principle experiments established that air-stable [(JosiPhos)NiCl2] precatalysts can be employed successfully in such transformations. Lighten Up: The substrate scope of the title reaction includes (hetero)aryl chloride, bromide, and tosylate electrophiles. The versatility and potential scalability of the reported method is demonstrated by the use of either commercially available stock solutions of ammonia or ammonia gas.

Diarylethene-modified nucleotides for switching optical properties in DNA

Diarylethenes were attached to the 5-position of 2′-deoxyuridine in order to yield three different photochromic nucleosides. All nucleosides were characterized with respect to their absorption and photochromic properties. Based on these results, the most promising photochromic DNA base modification was incorporated into representative oligonucleotides by using automated phosphoramidite chemistry. The switching of optical properties in DNA can be achieved selectively at 310 nm (forward) and 450 nm (backward); both wavelengths are outside the normal nucleic acid absorption range. Moreover, this nucleoside was proven to be photochemically stable and allows switching back and forth several times. These results open the way for the use of diarylethenes as photochromic compounds in DNA-based architectures.

Enhanced durability of linker-containing carbon nanotube functionalized via diazonium reaction

We present the fabrication of highly durable catalysts with the functionalized carbon nanotube (CNT) via diazonium chemistry for polymer electrolyte membrane fuel cell (PEMFC). The functionalization of the CNT with the thiolphenyl groups by diazonium coupling reaction was shown to enhance the dispersion of Pt nanoparticles with narrow size distribution deposited on the CNT surfaces as well as their electrochemical stability. The electrochemical analysis demonstrates that the Pt/functionalized CNT show higher electrochemical durability and catalytic activity than the Pt/unmodified CNT. The enhanced electrochemical performance of the Pt/functionalized CNT is attributed to the uniform distribution of Pt nanoparticles with smaller size and the strong interaction between Pt and the functionalized CNT support through the formation of Pt-sulfur bonding. This study shows that this simple functionalization of CNT by the in situ grafting of the thiolphenyl groups as the linker onto the surface is an effective way to fabricate a highly durable Pt catalyst for PEMFC, thus providing a design guide of the functionalized CNT support catalyst with a great potential as a PEMFC catalyst.

Design, synthesis, and biological evaluation of 1-substituted -2-aryl imidazoles targeting tubulin polymerization as potential anticancer agents

A series of novel 1-substituted-2-aryl imidazoles (SAI) were designed and synthesized based on our previously reported ABI (2-Aryl-4-Benzoyl Imidazole) analogs and on the structure of combretastatin A-4 (CA-4). These compounds showed potent antiproliferative activities against six human cancer cell lines with IC50 values in nano molar range. Among them, compound 3X exhibited the best anticancer activity with an average IC50 value of ?100 nM. The compound maintains the mechanism of action by inhibiting tubulin polymerization, thus causing cell arrest at G2/M phase and apoptosis. In vivo efficacy studies indicated that 3X was highly effective in suppressing tumor growth in a MDA-MB-468 xenograft model of nude mouse with a TGI (Tumor Growth Suppression) of 77% at 60 mg/kg without causing significant toxicity. In addition, 3X displayed significantly better water solubility (36.70 mug/mL) than CA-4 (2.83 mug/mL). Molecular modeling study indicated that 3X binds well to the colchicine binding site in tubulin. Our results suggest that the novel SAI analogs deserve further investigation as potential anticancer agents.
