An Environmentally Route for Synthesis of Triarylmethanes Catalyzed by Heteropolyphosphotungstic Acid in Water
An efficient and environmentally benign procedure for synthesis of triarylmethanes is developed via condensation of aromatic aldehydes and N,N-dimethylaniline using small quantity of heteropolyphosphotungstic acid (HPW) as catalyst in water. Good functional group tolerance, simple green experimental procedure, and good to excellent yields of products are the most advantages of this work.

In this work, an eco-friendly procedure for the preparation of 2,3-dihydroquinazoline-4(1H)-ones was developed by condensation reaction of benzylic and heterocyclic aldehydes with 2-aminobenzamide in the presence of catalytic amounts of cyanuric chloride (2,4,6-trichloro-1,3,5-triazin) as an available and inexpensive organo-catalyst under aqueous media as a green conditions. The new co...

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 fri...

full textMicrowave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid
Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
