Catalytic activation of C-N bond is 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 strategic exchange of metal nodes in a Cu-MOF with the Pd(II) ions. The 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 found to be size and shape selective for the substituents and recyclable at least for four catalytic cycles without losing itsactivity.
