of N-(2-SF5-ethyl)amines is reported via the SN2 reaction between various amines and 2-(pentafluoro-λ6-sulfanyl)ethyl trifluoromethanesulfonate as the SF5-containing electrophile. A total of 14 examples of SF5-containing aliphatic amines were synthesized, with yields going from 19 to 92%. Moreover, the effect of the SF5 substituent on the basicity and the lipophilicity of the amine was evaluated, and

1,4-Disubstituted 1,2,3-triazoles containing a pentafluorosulfanylalkyl group were synthesized in good to excellent yields (57-91%) by the click cycloadditions of in situ generated SF5-alkyl azides with aromatic and aliphatic alkynes. Nucleophilic substitution of the SF5 group was observed for the first time in a bench-top reaction. (C) 2010 Elsevier Ltd. All rights reserved.
