Two routes to RFIF6 compounds were investigated: (a) the substitution of F by RF in IF7 and (b) the fluorine addition to iodine in RFIF4 precursors. For route (a) the reagents C6F5SiMe3, C6F5SiF3, [NMe4][C6F5SiF4], C6F5BF2, and 1,4-C6F4(BF2)2 were tested. C6F5IF4 and CF3CH2IF4 were used in route (b) and treated with the fluoro-oxidizers IF7, [O2][SbF6]/KF, and K2[NiF6]/KF. The observed sidestep reactions
研究了制备R F IF 6化合物的两种途径:(a)在IF 7中用R F取代F,以及(b)在R F IF 4前体中向碘中添加氟。对于路线(a),试剂C 6 F 5 SiMe 3,C 6 F 5 SiF 3,[NMe 4 ] [C 6 F 5 SiF 4 ],C 6 F 5 BF 2和1,4-C 6 F 4(BF 2)2经过测试。在路线(b)中使用了C 6 F 5 IF 4和CF 3 CH 2 IF 4,并用了氟氧化剂IF 7,[O 2 ] [SbF 6 ] / KF和K 2 [NiF 6 ] / KF进行了处理。 。讨论了在路线(a)和(b)情况下观察到的回避反应。的C相互作用6 ˚F 5的SiX 3(X = Me中,F),C 6 ˚F 5 BF 2,1,4-C 6 ˚F 4(BF 2)2与IF 7仅给出相应的环氟化产物,全氟化环己二烯和环己烯衍生物,而[NMe 4 ] [C 6 F 5 SiF
