The Elusive Palladium-Diazo Adduct Captured: Synthesis, Isolation and Structural Characterization of [(ArNHC-PPh2)Pd(eta(2)-N2C(Ph)CO2Et)]
The first example of a diazo palladium adduct is reported. The complexes [(ArNHC-PPh2) M(eta(N2C)-N-2(Ph) CO2Et)] (M = Ni, 3; M = Pd, 4; ArNHC-PPh2 = 3-(2,6-diisopropylphenyl)- 1-[(diphenylphosphino)ethyl] imidazol-2-ylidene) were prepared by ligand exchange with styrene-coordinated precursors [(ArN...

| Resumo: | The first example of a diazo palladium adduct is reported. The complexes [(ArNHC-PPh2) M(eta(N2C)-N-2(Ph) CO2Et)] (M = Ni, 3; M = Pd, 4; ArNHC-PPh2 = 3-(2,6-diisopropylphenyl)- 1-[(diphenylphosphino)ethyl] imidazol-2-ylidene) were prepared by ligand exchange with styrene-coordinated precursors [(ArNHC @ PPh2) M(styrene)] (M = Ni, 1; M = Pd, 2). Complex 4 was fully characterized, including X-ray analyses; this constitutes the first example of a diazo adduct compound with palladium, thereby closing the gap between Groups 8 and 10 regarding this type of compounds. |
