1，3，5-三（三氟甲基）苯与丁基锂在乙醚/己烷中反应形成2，4，6-三（三氟甲基）苯基锂，其已通过低温单晶X射线分析和NMR方法表征;该分子以二聚体形式存在，其中每个锂通过与两个碳原子、乙醚分子的氧和来自邻-CF 3基团的两个氟键合而稳定。
1,3,5-Tris(trifluoromethyl)benzene reacts with butyl-lithium in ether/hexane to form 2,4,6-tris(trifluoromethyl)phenyl-lithium which has been characterized by low-temperature single-crystal X-ray analysis and NMR methods; the molecule exists as a dimer in which each lithium is stabilized by bonding to two carbon atoms, an oxygen of a diethyl ether molecule, and two fluorines from ortho-CF3 groups.
