Fluorinated alkyl groups are important motifs in bioactive compounds, pos. influencing pharmacokinetics, potency and conformation. The oxidative difluorination of alkenes represents an important strategy for their preparation, yet current methods are limited in their alkene-types and tolerance of electron-rich, readily oxidized functionalities, as well as in their safety and scalability. Herein, we report a method for the difluorination of a number of unactivated alkene-types that is tolerant of electron-rich functionality, giving products that are otherwise unattainable. Key to success is the electrochem. generation of a hypervalent iodine mediator using an “”ex-cell”” approach, which avoids oxidative substrate decomposition The more sustainable conditions give good to excellent yields in up to decagram scales. Of note, when handling HF reagents, personal protection is of utmost importance.
