Cover Feature: Intramolecular Hiyama Coupling: Synthesis of 1,8,13‐Trisubstituted Chiral Triptycenes with Three Different Substituents by Intramolecular Substituent Transfer (Chem. Eur. J. 39/2023)

The proximity of Si−O−Pd plays an important role not only in the formation of the oxy‐palladium species in intramolecular Hiyama coupling, but also in the activation of the silyl group to facilitate intramolecular substituent transfer. Various 1,8,13‐trisubstituted chiral triptycenes were synthesize...

Description
Summary:The proximity of Si−O−Pd plays an important role not only in the formation of the oxy‐palladium species in intramolecular Hiyama coupling, but also in the activation of the silyl group to facilitate intramolecular substituent transfer. Various 1,8,13‐trisubstituted chiral triptycenes were synthesized by using this reaction. More information can be found in the Research Article by T. Iwata, M. Shindo, and co‐workers (DOI: 10.1002/chem.202300988).
