General methods have not been previously developed for the synthesis of sterically hindered α-SCF3-substituted carbonyl compounds using nucleophilic trifluoromethylthiolating reagents. Thus, we herein report sp3C–SCF3 bond formation in hindered α-bromoamides containing 3-bromo-oxindoles and linear α-bromoamides using CuSCF3 or AgSCF3 under mild conditions to access sterically hindered α-SCF3-substituted

The synthesis of trifluoromethylthiolated ketenimines is herein described. They are easily synthesized from the corresponding α‐trifluoromethylthiolated oximes upon activation with triflic anhydride and a base. The presumed nitrilium ion resulting from the Beckmann rearrangement is deprotonated to lead to the key intermediate, whose stability brought by the fluorinated substituent was unforeseeable
