Synthesis and Characterization of Palladium Pincer Bis(carbene) CCC Complexes.

ABSTRACT: The metalation of the ^DIPPCCC (^DIPPCCC = bis(diisopropylphenyl-imidazol-2-ylidene)phenyl) ligand platform with Pd was achieved under mild conditions by reacting [H₃(^DIPPCCC)]Cl₂ with Pd(OAc)₂ at room temperature in the presence of 3.1 equiv of LiN(SiMe₃)₂. The resulting complexes (^DIPPCCC)PdX (X = Cl or Br) were oxidized by two-electron oxidants PhICl₂, Br₂, and BTMABr₃. All the complexes were crystallographically characterized, and analysis of structural parameters around the ligand scaffold show no evidence of a ligand-centered radical, rendering the metal center in the oxidized species, (^DIPPCCC)PdX₃ (X = Cl or Br), a formal Pd^IV<
