A bipyridine-based MOF-supported single-site palladium catalyst for efficient and recyclable carbonylation of aryl iodides to esters

Abstract

Herein, we report the design and synthesis of m-bpy-MOF-PdCl₂, a heterogeneous single-site palladium catalyst constructed via a mixed-linker metal–organic framework (MOF) strategy. In the carbonylation of iodobenzene, the catalyst exhibits exceptional activity under mild conditions without the need for a base. It also exhibits broad functional group tolerance, straightforward separation, and excellent recyclability over multiple cycles, with minimal loss of performance.
