synthesis and characterization of the new six- and seven-membered
Pd–PEPPSI-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–Miyaura
cross-coupling and catalytic dehalogenation of a range of aryl halide
substrates.
