A Ruthenium-catalyzed C–H activation strategy as an efficient shortcut in the total synthesis of 6,8-dimethoxy-1,3-dimethylisoquinoline
(Georg Thieme Verlag Kg, 2019-07)
A short and convenient total synthesis of 6,8-dimethoxy-1,3-dimethylisoquinoline, employing a C‒H activation/alkenylation strategy, is reported. It involved the CeCl3.7H2O-promoted methoximation of 2,4-dimethoxyacetophenone ...
Application of sulfonated nanoporous carbons as acid catalysts for Fischer esterification reactions
(Elsevier, 2015-06)
Heterogeneous acid catalysts were prepared by sulfonation of nanoporous carbons (NPCs). The NPCs were produced by pyrolysis of resorcinol-formaldehyde nanoporous resins (NPRs). The NPRs were synthesized as wet gels by ...
Effect of operating variables and kinetics of the lipase catalyzed transesterification of ethylene carbonate and glycerol
(MDPI AG, 2018-09-05)
Glycerol carbonate (GC) is a value-added product originating from the valorization of widely available glycerol (Gly), a side stream from the production of biodiesel. Here we approach the production of this chemical comparing ...
Singlet Oxygen Formation during the Oxygen Reduction Reaction in DMSO LiTFSI on Lithium Air Battery Carbon Electrodes
(Wiley-VCH, 2019-11)
Formation of singlet oxygen,1O2, during the O2 electroreduction reaction (ORR) on carbon electrode in Lithium bis‐(tri‐fluoromethylsulfonyl)imide (LiTFSI) dimethyl sulfoxide (DMSO) electrolyte has been detected “in‐operando” ...
Synthesis and properties of cleavable quaternary ammonium compounds
(Japan Oil Chemists’ Society, 2021-03)
Quaternary ammonium compounds are widely used as antiseptic and disinfectant. It is been a concern that their widespread use will lead to an increase of environmental problems, therefore the development of biodegradable ...
Synthesis and characterization of a novel series of 1,4-dihydropyridine analogues for larvicidal activity against Anopheles arabiensis
(Wiley Blackwell Publishing, Inc, 2017-09)
The new-fangled bis(4-substituted benzyl) 4-(4-substitued phenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate derivatives were synthesized by the union of substituted aryl aldehyde, tert-butyl acetoacetate, ammonium ...
REACTION OF O-AMINOBENZAMIDES WITH DIALKYL CARBONATES AND IONIC LIQUIDS: A NOVEL ONE-POT, HIGH-YIELD, MICROWAVE-ASSISTED SYNTHESIS OF 1-ALKYLQUINAZOLINE-2, 4-DIONES

Confined lithium–sulfur reactions in narrow-diameter carbon nanotubes reveal enhanced electrochemical reactivity
(American Chemical Society, 2018-10)
We demonstrate an unusual electrochemical reaction of sulfur with lithium upon encapsulation in narrow-diameter (subnanometer) single-walled carbon nanotubes (SWNTs). Our study provides mechanistic insight on the synergistic ...
