| Abstract: | A new class of hypervalent iodine reagents containing phthalimidate was synthesized, and structurally characterized by X‐ray analysis. The benziodoxole‐based reagent displays satisfactory solubility in common organic solvents and is reasonably stable in solution as well as in the solid state. The reagent was used for the oxidative amination of the C(sp3)? H bond of N,N‐dimethylanilines. In addition, the reagent was also applicable to oxidative amination with rearrangement of trialkylamines as well as enamines that were prepared in situ from secondary amines and aldehydes. |
