An efficient palladium catalyzed atom-economic synthesis of functionalized 9-(diarylmethylene)-9H-fluorenes has been accomplished in one-pot bis-coupling process using triarylbismuths as organometallic reagents. These bis-couplings in 1 hour short reaction time afforded various 9-(diarylmethylene)-9H-fluorenes in good to high yields. (C) 2011 Elsevier Ltd. All rights reserved.
