N-Heterocyclic Carbene-Catalyzed Trifluoromethylation of Aromatic N-Tosylaldimines
Nucleophilic trifluoromethylation of aromatic N-tosylaldimines has been achieved using trifluoromethyltrimethylsilane (TMSCF3) in the presence of the in situ generated N-heterocyclic carbene catalysts. Aromatic N-tosylaldimines with electron-withdrawing as well as electron-donating groups on the aryl ring afforded the corresponding trifluoromethylated sulfonamides in moderate to good yields.
