The synthesis of indenols and fulvenes was achieved through Rh-catalyzed C-H bond activation of simple and diverse arylketone derivatives and subsequent coupling with internal alkynes. The process was found to involve either an α or γ dehydration step, depending on the substrate disposition and representing diverse pathways toward functionalized fulvenes.

A good neighborhood! The metal‐catalyzed oxidativeCH functionalization of electron‐rich arenes is well‐established, but analogous reactions of electron‐poor substrates are rare. A new application makes use of common electron‐withdrawing functional groups (COMe, CONH2, CONEt2) in the rhodium‐catalyzed oxidative Heck reaction to generate complex organic molecules. Cp*= η5‐C5Me5.
