Functionalized Macrocyclic Ligands: Big Building Blocks for Metal Coordination
摘要:
Two large, conjugated, macrocyclic ligands, 5a and 5b, have been efficiently prepared from easily accessible precursors. Both macrocycles incorporate a 3,5-diethynylpyridine subunit, making them suitable for further elaboration, as demonstrated via their coordination to give Pt complexes 6a and 6b.
