Abstract
Sulfinates are important portals to various sulfonyl functional groups with wide applications and great societal impacts. The efficient synthesis of these versatile intermediates remains a key research topic in organosulfur chemistry. By employing Ni-electrocatalysis and SO2 as the sulfur source, our recent work on the room-temperature sulfinylation of a broad scope of readily available aryl iodides and electron-deficient bromides is presented. With the scalability of the e-sulfinylation demonstrated in both batch and flow settings, the practical use of SO2 stock solution is highlighted, and the preparation and titration of SO2 stock solution are detailed.
