Rapid Access to Triarylated Cyclotriveratrylenes from Threefold Couplings of CTV‐I 3 with Triarylbismuth Reagents

A series of C 3 ‐symmetric triiodocyclotriveratrylene (CTV‐I 3 ) derivatives have been successfully arylated to afford the corresponding triarylcyclotriveratrylene derivatives in high yields by using triarylbismuth compounds as threefold coupling reagents under palladium‐catalyzed conditions. This functionalization is valuable in the context of the development of new synthetic and coupling studies to rapidly access cyclotriveratrylene molecular skeletons with rigid and deeper cavities.
