Abstract

We report an improved, convenient, and general synthesis of the air-stable complex CpCo(DQ) (DQ = duroquinone), originally described by Schrauzer and Thyret in 1963, and applied this general protocol to the preparation of a series of related CpCo(p-benzoquinone) complexes with yields ranging from 35 to 96%. The complexes were characterized by single-crystal X-ray diffraction, and the bonding characteristics were compared to those of other CpCo–olefin complexes. Their catalytic performance was evaluated in cyclotrimerization reactions under both thermal and photochemical conditions for the synthesis of pyridine and benzene derivatives.

CpCo -苯醌配合物：方便的CpCo(I)预催化剂─合成与反应性

我们报道了一种改进的、方便的、通用的空气稳定配合物CpCo(DQ) （DQ = duroquinone）的合成方法，该方法最初由Schrauzer和Thyret于1963年描述，并应用该通用程序制备了一系列相关的CpCo（对苯醌）配合物，产率从35%到96%。用单晶x射线衍射对配合物进行了表征，并与其他cpco -烯烃配合物的成键特性进行了比较。在热和光化学条件下评价了它们在环三聚化反应中合成吡啶和苯衍生物的催化性能。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
