Visible‐Light‐Induced Thiocyanation of Unactivated Alkenes with N ‐Thiocyanatosaccharin via Remote Quinoxalinone Migration under Catalyst Free Conditions

A novel visible‐light‐induced thioacylation method has been developed for the functionalization of unactivated alkenes. This approach utilizes N ‐thiocyanatosaccharin as a source of SCN radicals, achieved via a photoredox passway, rather than requiring a conventional radical initiator like AIBN. The reaction proceeds via remote quinoxalinone migration. This metal‐ and catalyst‐free method serves as an efficient and environmentally friendly approach for the synthesis of distal thiocyanate‐substituted ketones.
