Abstract

Abstract: Herein we report the synthesis of a new abnormal N‐heterocyclic carbene ( a NHC)‐based ligand and its use in synthesizing an acetate bridged CH activated palladium dimer (1 ). In complex1, the carbene ligand displays an abnormal mode of binding with the palladium(II) ion. We used complex1 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 selectively the β‐arylated products in good to excellent yields.
