N-heterocyclic carbene (aNHC)-based ligand and its use in synthesizing an acetate bridged CH activated palladium dimer (1). In complex 1, the carbene ligand displays an abnormal mode of binding with the palladium(II) ion. We used complex 1 as a catalyst for the oxidative Heck coupling reaction of arylboronic acids with electron-deficient as well as electron-rich olefins at ambient temperature in water to produce

A palladium catalysed oxidative beta-arylation of an electron-richolefin is described. The reaction was under mild conditions; meanwhile, additives and directing groups are not needed. Various arylboronic acids worked well under the standard conditions.
