摘要:
[Cp*IrCl2](2) reacts with 2 equiv of Na2NCN to afford the NCN-bridged diiridium complex [Cp*Ir(mu(2)-NCN-N,N)](2) (5), which undergoes further reactions with donor molecules such as CO and phosphines. Complex 5 works as an excellent building block for the synthesis of the NCN-capped heterotrinuclear complexes [(Cp*Ir)(2)(ML)(mu(3)-NCN-N,N,N)(2)](+) (ML = Rh(cod), CpRu, Pd(eta(3)-C3H5)) on reactions with cationic group 8-10 metal complexes such as [Rh(cod)(acetone)](+), [CpRu(MeCN)(3)](+), and [Pd(eta(3)-C3H5)(acetone)(n)](+), while the dimerization of 5 leads to the cubane-type tetrairidium complex [Cp*Ir(mu(3)-NCN-N,N,N)](4).
