Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 20439-47-8, molcular formula is C6H14N2, introducing its new discovery.

The diastereospecific formation of dihydropyrimidines (DHPMs) has been achieved in moderate to high yields with up to 99% ee by a Biginelli reaction. The reaction was performed by using a combined catalyst consisting of a chiral bifunctional primary amine-thiourea 9f and a Bronsted acid with tert-butylammonium trifluoroacetate (t-BuNH2·TFA) as additive in dichloromethane at room temperature. The possible mechanism for the reaction has been proposed to explain the origin of the activation and the asymmetric induction.

A hairy cationic nanocellulose (CNCC) was prepared by a two-step reaction. First dialdehyde modified cellulose (DAMC) were prepared by periodate oxidation of cellulose fibers and subsequently DAMC fibers were cationized by a reaction between the aldehyde groups of cellulose and (2-hydrazinyl-2-oxoethyl)-trimethylazanium chloride [Girard?s reagent T (GT)] to produce cationic dialdehyde cellulose (CDAMC) fibers. Subjecting the suspension of CDAMC fibers to a hot-water treatment at 60 C, resulted in the formation of cationic rod-like nanocellulose (CNCC). Atomic force microscopy and transmission electron microscopy showed the CNCC has a width of 5 nm and a length about 120 nm. Zeta potential measurement, Fourier transform infrared spectroscopy, solid carbon-13 NMR and X-ray photoelectron spectroscopy confirmed the presence of cationic groups on CNCC. The positive charge content of CNCC is about 1.68 mmol/g measured by conductometric titration. CNCC has a crystalline index of 67 % and possesses cellulose I crystalline structure.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 123-46-6, you can also check out more blogs about123-46-6

In this work, the new polysaccharide-platinum conjugates of 5-aminosalicylic acid modified lycium barbarum polysaccharide linking platinum compounds were designed in order to construct an anticancer metal drug delivery system. The multiple analysis methods were used to describe the chemical structure and physical properties of the polysaccharide-metal conjugates. The results showed that 5-aminosalicylic acid successfully acted as linker which was covalently bound between polysaccharide and platinum compound. The morphology and rheological properties of polysaccharide have been changed by the formation of conjugates, which exhibited certain inhibition specificity to A549 (human lung cancer cell line). The agarose gel electrophoresis and fluorescence microscopy results demonstrated that such conjugates promoted the unwinding of DNA and could significantly damage the nucleus of A549 cells. Cell cycle analyzing the Pt complex of conjugates could cause intracellular DNA damage and induced G2 phase arrest. So, polysaccharide-platinum conjugates might find a range of applications, for example in metal anticancer drug delivery.

(equation presented) The first enantioselective ruthenium olefin metathesis catalysts have been prepared, and high enantiomeric excesses (up to 90%) are observed in the desymmetrization of achiral trienes. A model consistent with the stereochemical outcome of the reactions is described and suggests side-on olefin binding and reorganization of the halide ligands.

The chiral discrimination ability of permethylated glucopyrano-oligosaccharides toward amino acid 2-propyl ester hydrochlorides was evaluated using FAB mass spectrometry. In the given permethylated homo-oligosaccharides, permethylated beta-cello-oligosaccharide series (II) showed remarkably higher S-selectivity toward tryptophan ester salts (Trp-O-iPr+) independent of the numbers (n) of the glucopyranose unit (n = 2-5). The hexamer and heptamer of the permethylated beta-malto-oligosaccharide series (I) showed the very similar enantioselectivity to permethylated alpha- and beta-cyclodextrin.

Sodium-conducting solvent-free polymer electrolytes based on commercially available and inexpensive materials poly(oxyethylene), POE, and three different sodium salts (NaI, NaCF3SO3 and NaClO4) were prepared and exhaustively characterized. In order to minimize the environmental impact related to conventional film processing based on casting, a combination of lyophilization and hot-pressing was successfully applied. Contrary to film-casting, this new approach led to very homogeneous and pore-free films. This study suggests the obtained polymer electrolyte films as a promising route to enhance not only ionic conductivity but also mechanical properties. Furthermore, a preliminary work on salt blends hosted by POE shows that they strongly decrease melting point and crystallinity of the polymer electrolytes and paves the way for enhanced sodium-conducting materials.
