A new one pot and solvent-free synthesis of nickel porphyrin complex

CuCl2 Catalyzed Solvent-free One Pot Synthesis of Dihydropyrimidinones

Solvent-free One Pot Biginelli Method for Synthesis of new Dihydropyrimidinone compounds

An effective one-pot synthesis of dihydropyrimidinonoes in solvent free conditions using CuCl2 as an inexpensive and readily available reagent through Biginelli condensation reaction of aldehyde derivatives, 1,3-dicarbonyl compounds and urea is described. Excellent yields, short reaction times for formation of the products and simple work-up are attractive features of this green prot...

One-pot synthesis of Benzimidazole derivatives under microwave Irradiation and solvent-free condition

A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...

Solvent-free Promoted One-pot Synthesis of ٤H-quinolizine, pyrido[٢،١-a]isoquinoline and pyrido[١،٢-a] quinoline Derivatives

This work describes a fast, mild, convenient and simple method for preparing of nitrogen heterocyclic derivatives by MCR reaction under solvent-free condition.

One-Pot Synthesis of Phenytoin Analogs in Solvent free Conditions Via the Use of Pestle/ Mortar

 phenytoine derivatives were synthesized , via the  pinacol condensation  with the  reaction of 1,3- diphenyl- propane- 1,3- dione (benzyl) analogs with urea or thiourea in presence of slica gel and solid KOH as Solid phase catalyst  in the mortar / pestle at room temperatures. The reaction was completed at short reaction times (approximately 15min) and pure products were obtained with high yie...
