✦ Synopsis

The synthesis of a series of phosphine-functionalised macrocycles, 1 4 , is described. The combination of Nand 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 metals in proximity. Macrocycles >S are homotopic ligands which may form homodinuclear complexes of transition metals.

Chemistry is reported that allows for the synthesis and screening of phosphine ligands by standard combinatorial technology. To demonstrate the method, libraries of phosphine containing peptides were synthesized. Rhodium was complexed to the phosphine ligands while they were attached to the synthesi
