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

• New synthesis route leading to saturated NHC ligands functionalized in the 4-position of the backbone.
• Synthesis and characterization of the derived pyridine coordinated NHC–Pd(Cl(II) complex.
• Structural elucidation of the imidazolinium salt and the palladium 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.

The pyridine coordinated dichloridopalladium(II) NHC complex is accessible in five steps in good yields from cheap para-nitrophenyl.Figure optionsDownload as PowerPoint slide
