Abstract

Abstract : A heterometallic organic framework {Pb[Pd(bpydc)Cl2 ]DMF} n (1 ) (H2 bpydc = 2, 2′‐bipyridine‐5, 5′‐dicarboxylic acid) was synthesized via a one‐pot solvothermal method and characterized using thermogravimetric analysis, X‐ray photoelectron spectroscopy as well as powder and single‐crystal X‐ray diffraction. The crystal structure of1 indicates that, in metalloligand Pd(bpydc)Cl2, every Pd atom adopts a square planar coordination mode with two chloride ions and two nitrogen atoms from bpydc, and the carboxyl groups of Pd(bpydc)Cl2 connect Pb atoms to form a one‐dimensional chain along the crystallographic a ‐axis, which is interlinked via metalloligands to form a two‐dimensional layer structure. This complex is highly active, stable and recyclable as a catalyst for theSuzuki–Miyaura andHeck reactions of a wide range of aryl halides including electron‐rich and electron‐poor aryl iodides/bromides, affording the corresponding products in good to excellent yields.
