a water soluble, bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally friendly gre...

   In the present work, a fast, green and simple synthesis method for the production of silver nanoparticles (AgNPs) is introduced. Silver nanoparticles are currently among the most widely used man-made nano materials, present in a wide range of consumer products. Green chemistry is characterized by careful planning of chemical synthesis of silver nanoparticles to reduce adverse outcomes. S...

a simple, green synthesis of n-alkyl-3-acetyl-2-methylpyrrole derivatives using zno nanoparticles from the three component reaction of aliphatic amines, acetylacetone (as a 1,3-dicarbonyl compound) and α-haloketones under solvent-free condition is described.

cdse nanostructures were synthesized by using green chemical route as starch was used as capping agent. xrd, hr-tem, sead, uv and pl studies were made for structural and optical properties of the prepared sample. film morphology and the thickness measurement of n-cdse were carried out with afm analysis. i-v characteristics curve of this junction confirmed the formation of schottky contact betwe...

a highly efficient procedure for the synthesis of 1,8-dioxo-octahydroxanthenes under mild, green and solvent-free condition by using hosa as a dual role catalyst is described. this is the first report of catalytic activity of hosa.

in this article, simple, convenient synthesis of 2-aryl-1-arylmethyl-1h-1,3-benzimidazole (1,2-disubstitutedbenzimidazoles) via condensation of 1,2-phenylenediamine and aromatic aldehydes using sba-pr-so3h as a nanoporous solid acid catalyst in green protocol was reported.
