Abstract

Abstract: A new MOF‐supported heterogeneous palladium catalyst Pd/NBB‐1 has been synthesized successfully through the effective metal metathesis between Pd(CF3 COO)2 and NBB‐1. NBB‐1 is a two‐dimensional zinc metal‐organic framework constructed from 2‐aminoterephthalate (NH2 −H2 BDC) and 2, 2′‐bipyridine‐5‐carboxylate (HBPC) by solvothermal method. The replacement efficiency of Pd(II) to Zn(II) is up to 72% after only 24 hours, which is beneficial to the catalytic application. Pd/NBB‐1 with a low loading of 2 mol% works efficiently in the 1, 4‐addition reaction of arylboronic acids with α, β‐unsaturated ketones in air, and its catalytic activity keeps unchanged after 3 reaction cycles. This work provides a new strategy to effectively prepare supported noble metal/MOF catalysts, which would further increase the practical applications of metal‐organic frameworks. Abstract : A new heterogeneous palladium catalyst (Pd/NBB‐1) has been synthesized successfully through the effective metal metathesis. This MOF‐based catalyst displays good crystallinity with adequate thermal stability, and shows good catalytic and cyclic performance in the 1, 4‐addition reaction of aryl boronic acids with α, β‐unsaturated ketone in air.
