Pd‐Catalyzed Allylic Arylation for Divergent Access to CF 3 ‐Functionalized Fluorenes and Dibenzofulvenes

Key Points

• The aim is to develop a unified strategy for synthesizing CF3-functionalized fluorenes and dibenzofulvenes.
• Utilized palladium-catalyzed allylic arylation.
• Employed CF3–π–allyl–Pd complexes as key intermediates.
• Explored two distinct pathways: α-selective nucleophilic addition and intramolecular isomerization.
• First α-selective nucleophilic addition in CF3–π–allyl–Pd chemistry achieved CF3-fluorenes.
• Intramolecular Tsuji–Trost allylation produced CF3-dibenzofulvenes.
