Abstract

The poly(pyrazol-1-ylmefhyl)benzenes L1-L5 react with [PdCl ₂(NCMe)₂] or [PdClMe(COD)] to form dinuclear palladium complexes [{PdClX(3,5-Me₂pzCH₂)₂-1,2-C ₆H₄}₂] (X = Cl (1), Me (2)), [{PdCl ₂(3,5-Me₂pzCH₂)₂-1,3-C ₆H₄}₂] (3), palladium complexes [{Pd ₂(μ-Cl)₂Me₂(3,5Me₂pzCH ₂)₂-1,3-C₆H₄}] (4), [{Pd ₂(μ-Cl)₂X₂(3,5-Me₂pzCH ₂)₂-1,4-C₆H₄}] (X = Cl (5), Me (6)), [{Pd₂(μ-Cl)₂Cl₂(3,5-'Bu ₂pzCH₂)₂-1,4-C₆H₄}] (7), and tetranuclear [{Pd₂(μ-Cl)₂Cl₂(3,5Me ₂pzCH₂)₂}₂-1,4-C₆H ₄] (8). The structures of 1, 2 and 8 were confirmed by X-ray structure analysis. The complexes efficiently catalyse the coupling reaction of iodobenzene and butylacrylate at 80 °C
