Abstract: C 19 H 8 F 6 N 2 ,triclinic, P1 (no.2), a =7.762(2)Å, b =9.126(2) Å, c =13.315(3) Å, a =74.11(2)°, b =75.29(2)°, g =65.10(1)°,V =812.4Å 3 , Z =2, R gt(F) =0.034, wRref(F 2 ) =0.096, T =113 K. Source of materialTo astirred solution of 2-bromobenzonitrile and octafluorocyclopentene in the n-BuLi/hexane(5.00g,13.22 mmol) in THF (100 ml) was added dropwise a2 .5 mol/l n-BuLi (5.24 ml, 13.10 mmol) at 195 Kunder aN 2 atmosphere.Stirring was continued for 40 minutes, and then octafluorocyclo-pentene (0.9 ml) was slowly added to the reaction mixture, and the mixture was stirred for 3hours at 195 K.The reaction was stopped by the addition of water.Through aseries of routine operations, the title compound (2.07g, 5.5 mmol) was obtained in 82.5 %y ield, m.p. 398.2 -398.7 K.Chemical analysis -found: C, 60.35 %; H, 2.11 %; N, 7.40 %; calculated for C 19H8F6N2:C,60.33 %; H, 2.13 %; N, 7.41 %.NMR and IR data are available in CIF.
