A reduction of nitrobenzenes via the combination of KOH and isopropanol was established for the general synthesis of aniline derivatives. A metal catalyst isn't required in this alternative reduction reaction, and a series of nitrobenzamide compounds were chemoselectively reduced into the corresponding aminobenzamides in good to excellent yields. This reaction is operationally simple, and proceeds under mild conditions.

A hydroamination of unactivated alkynes and lithium bis­(fluorosulfonyl)­imide (LiN­(SO2F)2) is described under mild conditions, affording a single regioisomer of the sulfonyl fluorides. This method features broad functional group compatibility and delivers the target vinyl fluorosulfonimides in good to excellent yields. Moreover, gram-scale hydroamination of terminal and internal alkynes is achieved. Further transformations exploiting the reactivity of the vinyl fluorosulfonimide are subsequently developed for the synthesis of fluorosulfates and diphenyl sulfate.
