Chair-boat form transformation of piperazine-containing ligand toward the preparation of dirhenium metallacycles.
A new generation of a flexible bipyridine-based ligand, 1,4-bis(4-pyridyl)-piperazine, with two main stable states (chair and twist-boat forms) was employed in the construction of unusual dirhenium metallacycles.
