title: Ethynyl Benziodoxolone (EBX): Installing Alkynes the Reversed Way.
abstract: Umpolung of alkynes: The hypervalent iodine reagent EBX (ethynyl benziodoxolone) can be employed for the electrophilic introduction of alkynes. Aside from its unusual reactivity, mild reaction conditions and a high tolerance towards various functional groups are remarkable features of this stable reagent and its reactions.
