Abstract
This study shows that aryldiazonium salts can participate as electrophiles in gold‐catalyzed C–H arylation of arenes. Using 2‐diazo benzophenones, a gold‐catalyzed oxidation/C–H activation/cyclization sequence has been developed, leading to valuable fluorenones. Key parameters for the reaction to proceed in good yields are the introduction of electron‐donating groups, the use of PF6− as counteranion, and terpyridine as an auxiliary ligand.Keywords
