Pd(0) nanocatalyst stabilized on a novel agar/pectin composite and its catalytic activity in the synthesis of biphenyl compounds by Suzuki-Miyaura cross coupling reaction and reduction of o-nitroaniline.

Carbohydrate polymers

PMID: 29804998
Carbohydr Polym. 2018 Sep 01;195:45-52. doi: 10.1016/j.carbpol.2018.04.064. Epub 2018 Apr 21.

The most important parameters for the fabrication of metallic nanoparticles are their synthesis method and the selection of stabilizer. These properties influence durability, shape, size, distribution, and catalytic performance of metallic nanoparticles. Therefore, a novel agar/pectin composite (APC) was...

Reactions of [Rh(κ(2) -O,O-acac)(PMe3 )2 ] (acac=acetylacetonato) and α,ω-bis(arylbutadiynyl)alkanes afford two isomeric types of MC4 metallacycles with very different photophysical properties. As a result of a [2+2] reductive coupling at Rh, 2,5-bis(arylethynyl)rhodacyclopentadienes (A) are formed, which display intense fluorescence...

Controlling axial conformation in 2-arylpyridines and 1-arylisoquinolines: application to the asymmetric synthesis of QUINAP by dynamic thermodynamic resolution.

Journal of the American Chemical Society

Clayden J, Fletcher SP, McDouall JJ, Rowbottom SJ.

J Am Chem Soc. 2009 Apr 15;131(14):5331-43. doi: 10.1021/ja900722q.

Unlike related biphenyl compounds, 2-arylpyridines and 1-arylisoquinolines can be induced to adopt preferentially one of two axial conformations by the presence of a sulfinyl substituent adjacent to the Ar-Ar bond. In the case of more substituted biaryls, the compounds...

Well-defined N-heterocyclic carbenes-palladium(II) precatalysts for cross-coupling reactions.

Accounts of chemical research

PMID: 18774825
Acc Chem Res. 2008 Nov 18;41(11):1440-9. doi: 10.1021/ar800020y.

Metal-catalyzed cross-coupling reactions, notably those permitting C-C bond formation, have witnessed a meteoritic development and are now routinely employed as a powerful synthetic tool both in academia and in industry. In this context, palladium is arguably the most studied...

Structural characterization, gelation ability, and energy-framework analysis of two bis(long-chain ester)-substituted 4,4'-biphenyl compounds.

There are few examples of single-crystal structure determinations of gelators, as gel formation requires that the dissolved gelator self-assemble into a three-dimensional network structure incorporating solvent via noncovalent interactions rather than self-assembly followed by crystallization. In the solid-state structures...

Charge distribution in arylhydrazine-centered mixed valence compounds with smaller bridges (five to nine bonds between closest nitrogens).

The journal of physical chemistry. A

Nelsen SF, Schultz KP.
PMID: 19354243
J Phys Chem A. 2009 May 07;113(18):5324-32. doi: 10.1021/jp810645q.

Charge distribution in six aromatic-bridged, aryldialkylhydrazine-centered mixed valence radical cations is discussed through consideration of their optical spectra. The compounds considered have two 2-phenyl-2,3-diazabicyclo-[2.2.2]octane-3-yl (HyPh) charge-bearing units linked by a 1,4-phenylene bridge and its p-methoxyphenyl (HyAn) analogue, as well...

Intrauterine exposure to 2,3',4,4',5-pentachlorobiphenyl alters spermatogenesis and testicular DNA methylation levels in F1 male mice.

Polychlorinated biphenyls (PCBs) are synthetic biphenyl compounds with high toxicity. There are a total of 209 homologs, among which 2,3',4,4',5-pentachlorobiphenyl (PCB118) is one of the dioxin-like PCBs. PCB118 can accumulate in pregnant mice, leading to fetus directly exposure during...

The development of cannabinoid receptor type-1 (CB1R) modulators has been implicated in multiple pathophysiological events ranging from memory deficits to neurodegenerative disorders among others, even if their central psychiatric side effects such as depression, anxiety, and suicidal tendencies, have...
