Abstract

Abstract : An unstrained metal-containing macrocycle was ring-expanded by a ring-opening metathesis strategy, leading to the formation of a bimetallic dimeric macrocycle. The reaction is driven by coordination of a bulky ligand, 2, 6-lutidine, on the fourth coordination site of the palladium center. In the absence of metal, or with a less bulky ligand, the ring-expansion reaction does not proceed. Abstract : An unstrained palladium-containing macrocycle was expanded by a ring-opening metathesis strategy. This reaction was driven by coordination of a bulky ligand, 2, 6-lutidine, to the palladium center, enabling a monometallic macrocycle to transform into a bimetallic dimeric macrocycle.
