Herein, we disclose osmaelectrocatalyzed C−H activations that set the stage for electrooxidative alkyne annulations by benzoic acids. The osmium electrocatalysis enables site‐ and chemoselective electrooxidative C−H activations with unique levels of selectivity. The isolation of unprecedented osmium(0) and osmium(II) intermediates, along with crystallographic characterization and analyses by spectrometric...
Radical fluorosulfonylation is emerging as an appealing approach for the synthesis of sulfonyl fluorides, which have widespread applications in many fields, in particular in the context of chemical biology and drug development. Here, we report the first investigation of FSO2 radical generation under electrochemical conditions, and the establishment of a new and facile approach for the synthesis of...
