Preliminary batch experiments revealed that upon mixing tosyl-protected imidoyl dichloride 1 with 9 equivalents of cesium fluoride (CsF) in acetonitrile, the targeted trifluoromethylamino anionic species could be observed by F NMR after 2 hours (see Supplementary Information). Subsequent addition of benzyl bromide to the reaction crude afforded trifluoromethylamine 4 in 63% yield after 2 hours at 80 ºC. To the best of our knowledge, this represents a new disconnection for the preparation of Csp 3 -NCF3 compounds.
