Palladium-Catalyzed [3+2] Cycloaddition Reaction of (Diarylmethylene)-cyclopropa[b]naphthalenes with Arynes: An Efficient Synthesis of 11-(Diarylmethylene)-11H-benzo[b]fluorenes

[摘要]：A Pd-catalyzed [3+2] cycloaddition reaction of (diarylmethylene) cyclopropa[b]naphthalenes with arynes provided an efficient approach for the synthesis of 11-(diarylmethylene)-11H-benzo[b] fluorenes with good to excellent yields under mild conditions.
