Cross-dehydrogenative coupling of [small alpha]-C(sp3)-H of ethers/alkanes with C(sp2)-H of heteroarenes under metal-free condition

01-Oct-2015 | Srinivas Ambala; Thanusha Thatikonda; Shweta Sharma; Gurunadham Munagala; Kushalava Reddy Yempalla; Ram A Vishwakarm ..., Organic & Biomolecular Chemistry, 2015

Here we have developed an effective metal-free dehydrogenative coupling method wherein α-oxyalkyl radicals were generated from the various cyclic ethers to undergo coupling with variety of electron-deficient heteroarenes such as un/substituted iso-quinolone, quinoline, pyridine, pyrazine and ...


Production of solubilized and depolymerized carbohydrate from cellulose using non-catalytic, supercritical depolymerization in polar aprotic solvents

30-Sep-2015 | Arpa Ghosh; Robert Clinton Brown; Xianglan Bai, Green Chemistry, 2015

We report yields of solubilized and depolymerized carbohydrate from solvent processing of cellulose as high as 94% without use of catalysts. Cellulose was converted using a variety of polar aprotic solvents at supercritical conditions, including 1,4-dioxane, ethyl acetate, tetrahydrofuran, methyl ...


Phytochemical composition, antiparasitic and α–glucosidase inhibition activities from Pelliciera rhizophorae

28-Sep-2015 | López, Dioxelis; Cherigo, Lilia; Spadafora, Carmenza; Loza-Mejía, Marco A; Martínez-Luis, Sergio, Chemistry Central Journal , 2015

Background: Panama has an extensive mangrove area and it is one of the countries with the highest biodiversity in America. Mangroves are widely used in traditional medicine, nevertheless, there are very few studies that validates their medicinal properties in America. Given the urgent need for ...


Molecules, Vol. 20, Pages 17735-17746: Identification of Minor Benzoylated 4-Phenylcoumarins from a Mammea neurophylla Bark Extract

25-Sep-2015 | Dang, Bach Tai; Rouger, Caroline ; Litaudon, Marc ; Richomme, Pascal ; Séraphin, Denis ; Derbré, Séverine, Molecules, 2015

Through dereplication analysis, seven known Mammea coumarins were identified in a fraction obtained from Mammea neurophylla dichloromethane bark extract selected for its ability to prevent advanced glycation end-product (AGE) formation. Among them, a careful examination of the NMR dataset of ...


Reorientation of Isomeric Butanols: The Multiple Effects of Steric Bulk Arrangement on Hydrogen-Bond Dynamics

23-Sep-2015 | Oluwaseun O. Mesele; Anthony A. Vartia; Damien Laage; Ward H. Thompson, Journal of Physical Chemistry B, 2015

Molecular dynamics simulations are used to investigate OH reorientation in the four isomeric butanols in their bulk liquid state to examine the influence of the arrangement of the steric bulk on the alcohol reorientational and hydrogen-bond (H-bond) dynamics. The results are interpreted within ...


Hybrid-angle-energy dispersive low-power X-ray diffraction and fluorescence portable system for non-invasive study: Peak identification and object positioning corrections

20-Sep-2015 | Author(s): Ariadna Mendoza Cuevas, Jorge Fernández-de-Cossio Dorta-Duque, Microchemical Journal, 2015

Publication date: January 2016 Source:Microchemical Journal, Volume 124 Author(s): Ariadna Mendoza Cuevas, Jorge Fernández-de-Cossio Dorta-Duque EDXRD apparatus can be improved by multiple angle scanning implementing a hybrid system that take advantage of shorter acquisition time and ...


Toward Anisotropic Hybrid Materials: Directional Crystallization of Amphiphilic Polyoxazoline-Based Triblock Terpolymers

15-Sep-2015 | Tobias Rudolph; Moritz von der Lühe; Matthias Hartlieb; Sebastien Norsic; Ulrich S. Schubert; Christophe Boisson; Fr ..., ACS Nano, 2015

We present the design and synthesis of a linear ABC triblock terpolymer for the bottom-up synthesis of anisotropic organic/inorganic hybrid materials: polyethylene-block-poly(2-(4-(tert-butoxycarbonyl)amino)butyl-2-oxazoline)-block-poly(2-iso-propyl-2-oxazoline) (PE-b-PBocAmOx-b-PiPrOx). The ...

Effects of Exhaust Gas Dilution on the Laminar Burning Velocity of Real-World Gasoline Fuel Flame in Air

11-Sep-2015 | Atmadeep Bhattacharya; Deb Kumar Banerjee; Dmitrii Mamaikin; Amitava Datta; Michael Wensing, Energy & Fuels, 2015

The effects of exhaust gas recirculation (EGR) on the laminar burning velocity of a commercial gasoline fuel-air mixture have been studied both numerically as well as experimentally at atmospheric pressure. The experiments have been performed using the heat flux burner method. For numerical ...
