應用

This hydroxylamine-based reagent enables the iron-catalyzed selective transformation of thiols to sulfinamides under mild conditions without the use of precious metal catalysts or additional oxidants. This reagent is shelf stable and facilitates the reaction in a single step and under mild conditions.

An iron catalyzed reaction for the selective transformation of thiols (-SH) to sulfinamides (-SONH2 ) by a direct transfer of -O and free -NH2 groups has been developed. The reaction operates under mild conditions using a bench stable hydroxylamine derived

We report both an intermolecular C-H amination of arenes to access N-methylanilines and an intramolecular variant for the synthesis of tetrahydroquinolines. A newly developed, highly electrophilic aminating reagent was key for the direct synthesis of unprotected N-methylanilines from simple arenes.
