Non-Covalent Supported of l-Proline on Graphene Oxide/Fe(3)O(4) Nanocomposite: A Novel, Highly Efficient and Superparamagnetically Separable Catalyst for the Synthesis of Bis-Pyrazole Derivatives

A superparamagnetic graphene oxide/Fe(3)O(4)/l-proline nano hybrid that was obtained from the non-covalent immobilization of l-proline on graphene oxide/Fe(3)O(4) nanocomposite was used as a new magnetically separable catalyst for the efficient synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ol) d...

Descripción
Sumario:A superparamagnetic graphene oxide/Fe(3)O(4)/l-proline nano hybrid that was obtained from the non-covalent immobilization of l-proline on graphene oxide/Fe(3)O(4) nanocomposite was used as a new magnetically separable catalyst for the efficient synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ol) derivatives. The prepared heterogeneous catalyst was characterized using FTIR, TGA, DTG, XRD, TEM, SEM, and elemental analysis techniques. Short reaction times (5–15 min), excellent yields (87–98%), and simple experimental procedure with an easy work-up are some of the advantages of the introduced catalyst.
