چکیده

in this paper, fe3o4-chitosan nanoparticles were prepared by the immobilization of chitosan on the surface of fe3o4 nanoparticles. then, the 5-substituted hydantoins were synthesized from the condensation of aldehyde derivatives, ammonium carbonate and zinc cyanide as a well-known cyanating agent by the magnetic fe3o4-chitosan nanoparticles under neat conditions. fe3o4-chitosan nanocatalyst as a renewable hybrid catalyst was easily recovered by an external magnet and reused for 4 times without obvious drop in its catalytic activity. the purpose of this research was to provide an easy method for the synthesis of 5-substituted hydantoins in high yields and short reaction times by a robust and magnetic recoverable catalyst.

Magnetic Fe3O4 nanoparticles as a highly efficient catalyst for the synthesis of imidazoles under ultrasound irradiation

To be fairly general and catalyst is easily separated by magnetic devices and can be reused without any apparent loss of activity for the reaction. Fe3O4 nanoparticles were prepared by chemical coprecipitation method and was found to be a mild and effective catalyst for the efficient, one-pot, three-component synthesis of 2,4,5-trisubstituted imidazoles at room temperature under ultrasound irra...

Montmorillonite KSF as a very efficient heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles

Montmorillonite KSF has been used as an effective and non-toxic heterogeneous catalyst for one-pot synthesis of 5-substituted 1H-tetrazoles via [3+2] cycloaddition of sodium azide with a wide variety of nitriles. The reaction afforded high yields of the desired products in a short reaction time under mild reaction conditions. The catalyst can be recovered by simple filtration and reuse...
