Reaction of [Rh2(µ-CO)2(η-C5Me5)2] with N2CR1R2(R1 R2 H; R1 R2 CF3; R1 H, R2 CO2Et; R1 H, R2 CH : CH2) affords the dynamic complexes [Rh2(µ-CR1R2)(CO)2(η-C5Me5)2], whereas, reaction with [Pt(cod)2](cod cyclo-octa-1,5-diene), [Pt2(CO)2(η-C5H5)2], or [Pt(C2H4)(PPh3)2] gives, respectively, [Rh2Pt(µ-CO)2(cod)(η-C5Me5)2], [Rh2Pt(µ-CO)2(CO)2(η-C5Me5)2], and [Rh2Pt(µ-CO)2(CO)(PPh3)(η-C5Me5)2]; an X-ray diffraction study on the last complex reveals incipient triply-bridging carbonyl ligands.
[Rh2(µ-CO)2(η-C5Me5)2] 与 N2CR1R2(R1 R2 H;R1 R2 CF3;R1 H, R2 CO2Et;R1 H, R2 CH : CH2)反应生成动态配合物 [Rh2(µ-CR1R2)(CO)2(η-C5Me5)2],而与 [Pt(cod)2](cod 环辛-1,5-二烯)、[Pt2(CO)2(η-C5H5)2] 或 [Pt(C2H4)(PPh3)2] 反应分别得到 [Rh2Pt(µ-CO)2(cod)(η-C5Me5)2]、[Rh2Pt(µ-CO)2(CO)2(η-C5Me5)2] 和 [Rh2Pt(µ-CO)2(CO)(PPh3)(η-C5Me5)2];对最后一种配合物进行的 X 射线衍射研究揭示了初始的三重桥接羰基配体。
