Abstract: Hypervalent iodine (III) five-membered heterocycles have found broad application as atom-transfer reagents for organic synthesis. Among them, 1-Phenyl-1,2-benziodoxol-3-(1H)-one is known as a traditional benzyne precursor, but no further synthetic applications have been reported. Herein, we… read more here.
