Abstract:	BiCl₃ reacts with sodium 2,4,6-tris(trifluoromethyl)phenoxide (NaOR_4f) in ether solution to produce an unusual condensation product in which three OR_f functions have been coupled with the elimination of three fluorine atoms. The product is R_fOC₆H₂(CF₃)₂C(O)OR_f, which has been characterized spectroscopically and by X-ray crystallography (triclinic space group P 1; a = 8.958(1), b = 12.652(2), c = 13.722(2)Å, α = 89.596(8)°, β = 75.92(1)°, γ = 71.412(7)°, V = 1425.6(3)Å³, Z = 2). Bi(OR_f)₃ is believed to be an intermediate in this process. The carbonfluorine bond activation is not observed in the absence of BiCl₃.
