A mild Pd-catalyzed three-component cascade cyclization functionalization of o-iodostyrenes, internal alkynes and boron reagents for versatile boryl-functionalized indenes is presented.
A sequential three-component intermolecular carbopalladation/Heck cyclization/intermolecular C–H bond functionalization for versatile alkylated polyfluoroarenes containing an indene skeleton is presented.
A palladium-catalyzed divergent three-component reaction employing norbornene derivatives as controlled switches toward phosphonate-containing indenes and indanes (and bis-alkylphosphonate functionalized diindane scaffolds) was established.
A palladium-catalyzed allene–allene cross-coupling mechanism was established.
Forging Unsymmetrical COTs: Pd-catalyzed auto-tandem reaction via cyclization, carbopalladation, and C–H activation enables the first modular synthesis of fully substituted, unsymmetrical cyclooctatetraenes (COTs), a long-inaccessible scaffold.
