Oxo‐Thiolation of Cationically Polymerizable Alkenes Using Flow Microreactors

The present study describes the cationic oxo‐thiolation of polymerizable alkenes by using highly reactive cationic species generated by anodic oxidation. These highly reactive cations were able to activate alkenes before their polymerization. Fast mixing in flow microreactors effectively controlled chemoselectivity, enabling higher reaction temperatures. Highly reactive arylsulfonium ions generated by anodic oxidation provide oxo‐thiolation of polymerizable alkenes, such as styrenes, prior to their polymerization. Fast mixing based on flow microreactor systems enables this transformation at a higher temperature.
