Abstract

AbstractThe synthesis of 2‐(pentafluoro‐λ6‐sulfanyl)acetamides is described via an amidation reaction between 2‐(pentafluoro‐λ6‐sulfanyl)acetic acid, the SF5‐containing building block, and various amines. A total of 27 examples of SF5‐containing amides were synthesized, with isolated yields going from 43 % to quantitative. We showed that a 2‐(pentafluoro‐λ6‐sulfanyl)acetamide could be converted to a N‐(2‐SF5‐ethyl)amine and a SF5‐containing oxadiazoles. Finally, the effect of the SF5 substituent on the lipophilicity of the amide of a model compound was evaluated.
