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.

通过有效的合成后修饰方法合成钯基MOF及其对Heck型偶联反应的催化活性

在所有交叉偶联反应中，由于C–N键的高解离能，C–N键的催化活化是最具挑战性和探索最少的。在这里，我们通过与Pd（II）离子在Cu-MOF中进行金属节点的战略交换，合成了新的钯-二吡唑骨架（Pd-MOF）。Pd-MOF被证明是通过裂解芳基肼的C-N键形成C-C键的出色催化剂。发现该催化剂对取代基的尺寸和形状具有选择性，并且在至少四个催化循环中可循环使用而不会损失其活性。
