Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell
(Royal Society of Chemistry, 2015-10-02)
A dye-sensitized photoelectrosynthesis cell (DSPEC) has been prepared for the oxidation of alkenes to
epoxides and evolution of hydrogen using water as an oxygen source and sunlight. A Ru oxidation catalyst,
2,2+
, is ...
Scaling behavior of polymers at liquid/liquid interfaces
(American Chemical Society, 2015-09-14)
The dynamics of a polymer chain confined in a soft 2D slit formed by two immiscible liquids is studied by means of molecular dynamics simulations. We show that the scaling behavior of a polymer confined between two liquids ...
Glycoclusters as lectin inhibitors: comparative analysis on two plant agglutinins with different folding as a step towards rules for selectivity
(Elsevier, 2015-09-23)
The emerging physiological significance of carbohydrate (glycan) protein (lectin) recognition engenders the interest to design synthetic inhibitors with a high level of selectivity among natural sugar receptors. Plant ...
Allylic azide rearrangement in tandem with Huisgen cycloaddition for stereoselective annulation: synthesis of C-Glycosyl iminosugars
(American Chemical Society, 2015-12-09)
Allylic azide rearrangement is used. in,tandem with. intramolecular azide-alkene cycloaddition to give a triazoline that when subsequently decomposed in the presence of a nucleophile gives piperidines. The tandem reaction ...
Bi- to tetravalent glycoclusters presenting GlcNAc/GalNAc as inhibitors: from plant agglutinins to human macrophage galactose-type lectin (CD301) and galectins
(Royal Society of Chemistry, 2015-02-17)
Emerging insights into the functional spectrum of tissue lectins leads to identification of new targets for the custom-made design of potent inhibitors, providing a challenge for synthetic chemistry. The affinity and ...
One-pot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ring-fused benzimidazoles
(American Chemical Society, 2015-05-19)
A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction ...
RAFT polymerization in supercritical carbon dioxide based on an induced precipitation approach: synthesis of 2-ethoxyethyl methacrylate/acrylamide block copolymers
(Wiley, 2015-05-13)
A new controlled/living heterogeneous polymerization technique using RAFT in benign supercritical CO2 is described involving the formation of monomer-swollen seed particles by precipitation of macroRAFT agent prior to ...
Experimental and kinetic modeling study of the shock tube ignition of a large oxygenated fuel: tri-propylene glycol mono-methyl ether
(Elsevier, 2015-05-13)
Tri-propylene glycol monomethyl ether (TPGME) is an important oxygenated fuel additive that can be used to reduce soot in diesel engines. However, a validated chemical kinetic model that incorporates the low- to high-temperature ...
An experimental and kinetic modeling study of n-hexane oxidation
(Elsevier, 2015-09-11)
Ignition delay times for n-hexane oxidation have been measured in a rapid compression machine (RCM) at stoichiometric conditions and at 15 bar. Due to the high reactivity of n-hexane and non-ideal experimental effects ...
Revisiting the kinetics and thermodynamics of the low-temperature oxidation pathways of alkanes: a case study of the three pentane isomers
(American Chemical Society, 2015-03-23)
This paper describes our developing understanding of low-temperature oxidation kinetics. We have investigated the ignition of the three pentane isomers in a rapid compression machine over a wide range of temperatures and ...
