1,3,5-Tribromobenzene can undergo a mono lithium-halogen exchange reaction to yield 3,5-Br2C6H3Li which can subsequently react with a perfluoroalkylether ester, RfORfC(O)OC2H5, yielding the aryl ketone 3,5-Br2C6H3C(O)RfORf. A classical SF4/HF reaction of this ketone yields the perfluoroalkylether benzene, 3,5-Br2C6H3CF2RfORf. This process can be repeated stepwise until all bromines are substituted
1,3,5-三溴苯可以进行单
锂-卤素交换反应,生成3,5-Br 2 C 6 H 3 Li,随后可以与
全氟烷基醚酯R f OR f C(O)OC 2 H 5反应,得到芳基酮3,5-Br 2 C 6 H 3 C(O)R f OR f。该酮的经典SF 4 / HF反应生成
全氟烷基醚苯,3,5-Br 2 C 6 H 3 CF 2 R f OR f。可以逐步重复该过程,直到所有
溴被取代,得到最终产物1,3,5-C 6 H 3(CF 2 R f OR f)3。R f OR f被选择为C 3 F 7 O [CF(CF 3)CF 2 O] 2 CF(CF 3)。可以选择其他
全氟烷基和
全氟烷基醚酯或其他亲电子试剂以与各种
有机锂中间体反应。
