One-pot and one-step novel N-methylation of 2,6-diaminopyridine
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 162-167
Abstract
2,6-diaminopyridine is extensively used as a pharmaceutical intermediate and a hair dye coupler as oxidation formulations. It is soluble in protic solvents. Primary and secondary amines are N-methylated by various methods such as direct alkylation of amines with Hofmann mechanism, but in many of these ... Read More)
1-Carboxymethyl-3-methylimidazolium chloride {[cmmim]Cl} as an efficient catalyst for the solvent-free synthesis of bis(indolyl)methanes
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 168-172
Abstract
1-Carboxymethyl-3-methylimidazolium chloride {[cmmim]Cl} is utilized as a highly efficient and reusable catalyst for the synthesis of bis(indolyl)methanes by the condensation reaction of indole with arylaldehydes under solvent-free conditions at room temperature. In summary, the presented method have ...

Ag nanoparticle/melamine sulfonic acid supported on silica gel as an efficient catalytic system for synthesis of dihydropyrimidin thiones
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 180-186
Abstract
3,4-dihydropyrimidin-2(1H)-thiones were synthesized in the presence of Ag nanoparticle/melamine sulfonic acid (MSA) supported on silica gel. The reaction was carried out at 110 oC for 20 min under solvent free conditions. In all cases, the three component reaction proceeded smoothly to give the corresponding ... Read More)
Caesium carbonate as a highly efficient catalyst for the synthesis of macrocyclic diamides
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 187-195
Abstract
In this research work, we report the synthesis of macrocyclic diamides from the reaction of diesters and aliphatic diamines in the presence of caesium carbonate. It has been demonstrated that among the carbonate of alkali metals (Li2CO3, Na2CO3, K2CO3 and CS2CO3), CS2CO3 appear to be the best catalyst ... Read More)
Synthesis, characterization and swelling behavior investigation of gelatin-g-Poly(Acrylic Acid-co-Itaconic Acid)
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 196-208
Abstract
A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization ... Read More)
The computational study of adsorption of carbon monoxide on pristine and Ge-doped (6,0) zigzag models of BNNTs
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, Pages 209-221
Abstract
The aim of this research is studying the effects of Ge-doped on CO adsorption on the outer and inner surfaces of (6, 0) zigzag model of boron nitride nanotube (BNNTs) by using DFT theory. For this purpose, eight models of CO adsorption on the surfaces of BNNTs are considered. At first step, all structures ... Read More)
The effect of sulfuric acid on pore initiation in anodic alumina formed in oxalic acid
