The synthesis and characterization of the new six- and seven-membered Pd鈥揚EPPSI-type N-heterocyclic carbene (NHC) complexes 3 and 4 is described. Complexes of the general formula [Pd(NHC)(3ClPy)Cl₂] (NHC = 6- or 7-Mes, 3ClPy = 3-chloropyridine) are accessed via the oxidation of the well-defined parent palladium(0) complexes 1 and 2. Complexes 3 and 4 have been employed in Suzuki鈥揗iyaura cross-coupling and catalytic dehalogenation of a range of aryl halide substrates.
