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)

Abstract

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).
