The first metal free selective C-F bond activation of a CF3 group was observed with N-heterocyclic silylenes [PhC(NtBu)2SiCl] (1) and [CH{(CCH2)(CMe)(2,6-iPr2C6H 3N)2}Si] (2) with PhNC(CF3)2. The reaction proceeds in a 1:1 molar ratio to yield the mono C-F bond activated products 3 and 4 with each containing a CF2 group. Both the reactions proceed through an unprecedented selective activation of one of the C-F bonds rather than forming the [1+2] cycloaddition product containing the three-membered SiNC rings.
