Synthesis and characterization of a 4-nitrophenyl functionalized NHC ligand and its palladium(II) complex

The synthesis and characterization of a novel pyridine coordinated dichloridopalladium(II) NHC complex is described. This compound possesses a saturated NHC ligand that is substituted with a para-nitrophenyl function in the 4-position of the NHC backbone. It is accessible in four steps with overall good yields starting from 4-nitro acetophenone.
