N-杂环卡宾(NHCs)是有机金属化学中重要的辅助配体，虽然已经合成了许多变体，但到目前为止最常见的是基于五元环的，如咪唑或苯并咪唑。与通常是共轭的五元环上的NHC络合物不同，对六元环NHC变体的探索主要集中在非共轭形式，如ASN，N‘-二氨基卡宾。关于共轭六元环NHC的报道仅限于具有周围胺支架的金属络合物，这些金属络合物的电子数在6到8个d之间(在第8-10族金属上)。这份手稿展示了四个d10金属配合物与周围丁支架的合成。金和银的络合物具有线性几何构型，而铜和铂的络合物是三配位的。用单晶X-射线单晶衍射法、多核核磁共振和其他光谱方法对所有配合物进行了表征。
N-Heterocyclic carbenes (NHCs) are vital auxiliary ligands for organometallic chemistry, and although many variants have been synthesized, by far the most common are based on five-membered rings, such as imidazole or benzimidazole. Unlike NHC complexes built on five-membered rings, which are typically conjugated, exploration of six-membered-ring NHC variants has focused on nonconjugated versions, such asN,N′-diamidocarbenes. Reports of conjugated six-membered ring NHCs are limited to metal complexes with a perimidine scaffold that are in a narrow range of between six and eight d electrons (on metals from groups 8–10). This manuscript showcases the synthesis of four d10metal complexes with a perimidine scaffold. The gold and silver complexes have a linear geometry, while the copper and platinum complexes are three-coordinated. All complexes were characterized by single-crystal X-ray crystallography, multinuclear NMR, and additional spectroscopic methods.
