New nickel(O) complexes with bulky diphosphine ligands
摘要:
The synthesis and characterization of new complexes of formula Ni(dp), Ni(dp)C7H8 (dp = 1, 2-bis-dicyclohexylphosphino)ethane [dcpe]; 1,3-bis(dicyclohexylphosphino)propane [dcpp]; 1,4-bis(dicyclohexylphosphino) butane [dcpb]), Ni2(dcpe)3, Ni2(dcpb)3, Ni(dcpe)2 and Ni(depe)2 (depe = 1,2-bis(diethylphosphino)-ethane) are described. The electronic spectra of these complexes are discussed.
