Abstract

Abstract : The complete exchange of metal nodes in a MOF with the Pd(ii ) ions was done without losing the structural integrity. The new MOF turned out to be an excellent catalyst for the C–C bond formation via un-reacted cleavage C–N bond of arylhydrazines. Abstract : The catalytic activation of the C–N bond is the most challenging and least explored amongst all cross-coupling reactions because of the high dissociation energy of the C–N bond. Herein, we synthesized a new palladium-di-pyrazole framework (Pd-MOF ) through the strategic exchange of metal nodes in a Cu-MOF with Pd(ii ) ions. Pd-MOF proved to be an excellent catalyst in forming a C–C bond via cleavage of the C–N bond of arylhydrazines. The catalyst was found to be size and shape-selective for the substituents and recyclable for at least four catalytic cycles without losing its activity.
