Silica Gel as a Promoter of Sequential Aza-Michael/Michael Reactions of Amines and Propiolic Esters: Solvent- and Metal-Free Synthesis of Polyfunctionalized Conjugated Dienes
(Wiley-V C H Verlag Gmbh, Weinheim, 2018)
We present an efficient, simple, metal- and solvent-free silica-gel-promoted synthesis of functionalized conjugated dienes by sequential aza-Michael/Michael reactions by starting from commercially available primary amines ...
Origin of Fluorine/Sulfur Gauche Effect of beta-Fluorinated Thiol, Sulfoxide, Sulfone, and Thionium Ion
(American Chemical Society (ACS), 2015)
The well-known gauche preference in FCCX systems, where X is an electronegative element from Period 2, is widely exploited in synthetic, medicinal, and material chemistry. It is rationalized on the basis of sigma(C-H)->sigma*(C-F) ...
Palladium-copper bimetallic surfaces as electrocatalysts for the ethanol oxidation in an alkaline medium
(Elsevier, 2023)
Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C), and ...
A theoretical study on borenium ion affinities toward ammonia, formaldehyde and chloride anions
(Royal Soc Chemistry, Cambridge, 2015)
Various borenium ion affinities toward three ligands (L' = NH3, HCHO and Cl-) have been evaluated by DFT calculations in the gas-phase and in solvent (CH2Cl2). The gas-phase results have been rationalized on the basis of ...
Partial purification and characterization of midgut leucyl aminopeptidase of Morimus funereus (Coleoptera : Cerambycidae) larvae
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Exopeptidases of Morimus funereus larvae were partially purified and characterized. Specific leucyl aminopeptidase (LAP) activity was increased eight-fold by gel filtration of the crude midgut extract. The partially purified ...
TiO2/WO3 photocatalytic composite coatings prepared by spray pyrolysis
(Elsevier, 2014)
TiO2/WO3 composites supported on a stainless steel foil were prepared by the spray pyrolysis technique. Content of WO3 was gradually increased from 1 wt% to 100 wt.%, while the coating thickness was limited to about 1 pm. ...
Overcoming hydrolysis of raw corn starch under industrial conditions with Bacillus licheniformis ATCC 9945a alpha-amylase
(Springer, New York, 2016)
alpha-Amylase from Bacillus licheniformis ATCC 9945a (BliAmy) was proven to be very efficient in hydrolysis of granular starch below the temperature of gelatinization. By applying two-stage feeding strategy to achieve ...
