摘要：
By the treatment of 0.3 molar amount of NbCl5 and LiAlH4, o-arylated α,α,α-trifluorotoluenes afforded fluorene derivatives in good yields. C-F bonds of the CF3 group and the neighboring ortho C-H bond were doubly activated to give the coupling products. Copyright © 2006 American Chemical Society.
