Selective [beta]-Arylation of Thiophenes with Aryl Iodides Catalyzed by Dinuclear Palladium Carboxylate Complexes

Novel dinuclear palladium complexes bearing acetoxy ligands were synthesized and characterized by X-ray crystal analysis. The complexes were utilized for the arylation of 2-ethylthiophene with iodobenzene to give ethylphenylthiophenes with high [beta] selectivity. The [beta]-arylation was also appli...

Description
Summary:Novel dinuclear palladium complexes bearing acetoxy ligands were synthesized and characterized by X-ray crystal analysis. The complexes were utilized for the arylation of 2-ethylthiophene with iodobenzene to give ethylphenylthiophenes with high [beta] selectivity. The [beta]-arylation was also applied to a variety of iodoarenes and thiophenes, except those bearing conjugated carbonyl substituents.
