The reactions of hexafluorobenzene, octafluorotoluene, decafluorodiphenyl, and octafluoronaphthalene with ethereal solutions of methylmagnesium iodide in the presence of AgCl or CuI gave the products of the methylation and 1-ethoxy-ethylation of the perfluorinated substrates, whose formation has been suggested to occur with participation of free radicals. Substitution of fluorine atoms by the 1-ethoxyethyl
在AgCl或CuI的存在下,六氟苯,八氟甲苯,十氟联苯和八氟萘与甲基碘化碘的醚溶液反应,得到全氟化底物的甲基化和1-乙氧基乙基化的产物,已表明它们的形成是通过参与而发生的。自由基。在C 6 F 5 CF 3和C 6 F 5 C 6 F 5中的1-乙氧基乙基取代氟原子的过程主要是对位。在C 10 F 8中,1-和2-方向发生的程度相同,而甲基基团主要攻击八氟萘的1-位,并且在与八氟甲苯的反应中显示出低的选择性。
