Radical reaction of alkyl iodides with trifluoromethyl phenylsulfonyl oxime ether 10 and hexamethylditin at 300 nm in benzene afforded the corresponding trifluoromethyl oxime ethers 11 in high yields, which were reduced into the 2,2,2-trifluoroethyl amines with lithium aluminium hydride. The trifluoroethyl amines could be converted into the corresponding trifluoromethyl ketones by treatment with NBS
烷基碘与三氟甲基苯基磺酰基肟醚10和六甲基二锡在苯中的自由基反应在300nm下以高收率得到相应的三氟甲基肟醚11,其用氢化铝锂还原为2,2,2-三氟乙胺。通过用NBS和DBU处理,可以将三氟乙基胺转化为相应的三氟甲基酮。
