Stepwise construction of a metallocatenane based on non-labile bis(terpyridine)-CdII complexes

Chem Commun (Camb). 2024 Jul 25;60(61):7914-7917. doi: 10.1039/d4cc02919d.

Abstract

A series of metalloligands bearing homoleptic 2,2':6',2''-terpyridine (tpy)-CdII complexes has been successfully synthesized. The formation of ML1 was accomplished through a sequence of Suzuki-Miyaura coupling and complexation reactions, offering an alternative method to produce tpy-based metalloligands under relatively mild conditions. Moreover, the metallomacrocycle C1 and metallocatenane C2 were self-assembled from heteroleptic complexation reactions involving ML1 and suitable counterparts.
