Functionalized Metalated Cavitands via Imidation and Late-Stage Elaboration

Efficient methods for the preparation of functionalized metallated cavitands are described. Functional groups can be either introduced by an imidation of metal-oxo complexes or by a late- stage elaboration of the imido ligands. By using diversified iminophosphorane (PPh₃=NR) reagents, π-conjugated p...

Opis
Sažetak:Efficient methods for the preparation of functionalized metallated cavitands are described. Functional groups can be either introduced by an imidation of metal-oxo complexes or by a late- stage elaboration of the imido ligands. By using diversified iminophosphorane (PPh₃=NR) reagents, π-conjugated pyrene, redox active ferrocene and polymerizable norbornene moieties were successfully introduced. Furthermore, the iodo and alkynyl groups on the imido ligands are capable of undergoing efficient Sonogashira cross-coupling and copper-catalyzed azide alkyne cycloaddition reactions, thereby providing facile access to complex architectures containing metallated cavitands.
