One-pot synthesis of functionalized bis(trifluoromethylated)benziodoxoles from iodine() precursors

Bis(trifluoromethylated)benziodoxoles (Bx) are broadly used cyclic hypervalent iodine reagents due to their stability and unique chemical properties. However, current methods to access them require several steps and long reaction times, making their synthesis tedious. Herein, a direct one-pot synthesis of bis(trifluoromethylated) Bx reagents from iodine( i ) precursors is reported, enabling the synthesis of functionalized reagents. A one-pot synthesis of bis(trifluoromethylated)benziodoxoles from iodine( i ) precursors has been developed. This method tolerates multiple functional groups on both alkyne and aromatic backbone.
