Treatment of 1-(5-bromo-2-chloro-6-methylpyrimidin-4-yl)-1-methylhydrazine with dimethylthiocarbamoylchloride gave 7-chloro-N,N,1,5-tetramethyl-1H-pyrimido[4,5-e][1,3,4]thiadiazin-3-amine in basic acetonitrile. The latter compounds were reacted with secondary amines in boiling ethanol to afford the related 7-amino derivatives.

In this research, the characteristics of CMP dioxane lignin (hardwood origin) and soda bagasse lignin (ethanol soluble fraction) and dioxane lignin of bagasse were studied using gel permeation chromatography, gas chromatography-mass spectrometry and 13C NMR spectroscopy and DFRC degradation procedure. The results indicated that the main structural units in lignins are phenyl propane skeletons b...

Ethanol (C2H6O) sensitivity of zinc oxide (ZnO) thin film has been studied in present work. Semiconductor thin films of zinc oxide (ZnO) were deposited onto alkali-free glass substrates by the sol–gel method and dip-coating technique. The ZnO sol was synthesized by dissolving zinc acetate dehydrate in ethanol, and then adding Tetra ethanol-amine.  The as-coated films were preheated at 150 ºC fo...

New novel derivatives of N-((5-((6-oxido-6-(4 substituted phenoxy)-4,8-dihydro-1H-[1,3,2] dioxaphosphepino [5,6-c]pyrazol-1-yl) methyl)-1,3,4-thiadiazol-2-yl)carbamoyl) substituted benzene sulfo namides (7a-o as depicted in scheme) were Synthesized by condensation reaction of 4substituted Phenyl phosphorodichloridates (6a-c) and N-((5-((4,5-bis(hydroxymethyl)-1H-pyrazol-1-yi)methyl)1,3,4-thiadi...

Herein described is a facile preparation protocol by which amino-alcohol derivatives of graphene oxide (GO) can be conveniently synthesized in high yield and short time an ultrasound treatment ethanol-graphite-oxide suspensions amines. Linear primary amines different chain length rapidly react with graphite oxides prepared from powder flakes, leading to the formation GO derivatives. Characteriz...

Abstract A series of neutral C,N,N Au(III) complexes were synthesized with N-(8-quinolinyl)benzamide derivatives or chiral N-[2-(1,3-oxazolin-2-yl)phenyl]benzamide derivatives. The convenient synthesis method for the amide ligands, together their operationally simple complexation by direct C–H auration, permitted changes to both steric and electronic properties promoting catalytic three-compone...

By connecting tercarbazole (3Cz) and triphenyltriazine (TRz) units with a diphenyl ether group, we designed synthesized new donor-spacer-acceptor structure molecule 9′-(4-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenoxy) phenyl)-9′H-9,3′:6′,9″-tercarbazole (3Cz-o-TRz) as the multifunctional component of exciplex emitters. As expected, intermolecular charge-transfer transition is dominant for 3Cz-o-T...

In the present study, we report synthesis and catalytic activity of tungsten- molybdenum-promoted mesoporous metal oxides in aminolysis epoxides. The as-synthesized catalysts were fully characterized by a variety techniques such as transmission electron microscopy (TEM), scanning (SEM), temperature-programmed reduction (TPR) desorption (TPD), nitrogen sorption measurements, powder X-ray diffrac...
