The synthesis of a series of phosphine-functionalised macrocycles, 1–6, is described. The combination of N-and O-sites with P- and S-sites provides ligands which may bind transition or non-transition metal ions; as a consequence, they give access to dinuclear complexes containing both a Lewis acid and a redox metallic site. Compounds 1,2 and 6 are heterodinucleating ligands capable of binding two dissimilar
描述了一系列由膦官能化的大环1-6的合成。N-和O-位与P-和S-位的结合提供了可以结合过渡或非过渡金属离子的配体。结果,它们可以访问含有路易斯酸和氧化还原金属位点的双核络合物。化合物1,2和6是能够在附近结合两种不同金属的异二核配体。大环3–5是同位配体,可以形成过渡金属的同核复合物。
