Substrate-initiated radical relay: redox-neutral iodo/bromo sulfoximination of alkynes

Key Points

• The reaction produces (E)-β-haloalkenyl sulfoximines selectively under mild conditions.
• Halogen radicals and sulfoximinyl radicals are formed in situ during the process.
• This approach enables metal-free conditions for sulfoximination reactions.
• The findings suggest a new method for creating halogenated compounds from alkynes.
