Cover Feature: Quadruple Role of Pd Catalyst in Domino Reaction Involving Aryl to Alkyl 1,5-Pd Migration to Access 1,9-Bridged Triptycenes (Chem. Eur. J. 45/2021) Based on mechanistic investigations, a single Pd catalyst functions as Pd SP 0 sp , Pd SP II sp and Pd SP IV sp species to catalyze four distinct processes: 1) aryl-to-alkyl 1,5-Pd migration, 2) intramolecular arylation, 3) homocoupling of phenylboronic acid and 4) Suzuki coupling.
