Unexpected Transfer of Tosyl Group of ArCHNTs-Catalyzed by N-Heterocyclic Carbene

Reactions of N-tosylimines with aziridines and electron-deficient unsaturated compounds in the presence of catalytic amount of NHC afforded unexpected tosyl group transfer products in good to high yields, which represent a new reaction pattern for imines as well as for catalysis of NHC.
