A one-pot, multicomponent strategy was used to synthesize the first example of the dirhenium carbonyl coordination complex , in which the two metal atoms are connected through a chiral helical-shaped diphosphine oxide. Thanks to the flexibility of the helix of helicene , complex was isolated in quite a good yield as a stable compound. It was characterized by analytical and spectroscopic techniques as well as by single-crystal X-ray analysis, which confirmed the chemical structure and the peculiar architecture of . In addition, computational studies were in agreement with the transitions observed in the experimental UV-vis spectrum, revealing the presence of two bands with maxima at about 520 (metal-to-ligand charge transfer) and 400 nm (IL).
采用一锅多组分策略合成了首例二铼羰基配位络合物，其中两个金属原子通过手性螺旋状二膦氧化物相连。由于螺旋烯螺旋的柔韧性，络合物 作为一种稳定化合物以相当高的产率被分离出来。通过分析和光谱技术以及单晶X射线分析对其进行了表征，证实了 的化学结构和独特结构。此外，计算研究与实验紫外可见光谱中观察到的跃迁一致，揭示了在约520 nm（金属到配体电荷转移）和400 nm（IL）处有两个最大值的谱带的存在。
