A new palladium(II) complex of a functionalized N-heterocyclic carbene: Synthesis, characterization and application in Suzuki–Miyaura cross-coupling reactions

Abstract trans -[PdBr 2 (NHC)Im] was prepared by reacting the corresponding imidazolium (Im) salt with palladium(II) acetate in dimethylsulfoxide in an in-situ reaction without generating a free carbene. Both the salt and the complex were characterized spectroscopically and by X-ray structure analysis. The complex was tested in homogeneous Suzuki–Miyaura cross-coupling reactions.
