Oxo‐Thiolation of Cationically Polymerizable Alkenes Using Flow Microreactors

Abstract

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.

Investigation of Parameter Control for Electrocatalytic Semihydrogenation in a Proton-Exchange Membrane Reactor Utilizing Bayesian Optimization

“…Electrochemical synthesis, which largely entails reactions driven by electricity, has attracted considerable attention in sustainable development (Johnson et al, 2017;Moeller, 2018;Sauermann et al, 2018;Ashikari et al, 2019;Shida et al, 2019;Yano et al, 2020;Zhou et al, 2020;Dong et al, 2021). An important characteristic of electrochemical reactions is the reduction of energy losses.…”

Convergent approach of double intermediates in flow microreactor: flash irreversible carbocations generation enables direct cross–coupling

“…2c). 19 These results indicate that the flow microreactor plays a crucial role in the rapid generation of carbocations by adding superacids. Accurate controllability of the reaction time 20,21 and temperature is also a significant characteristic of flow microreactors 22,23 We have previously reported that the controllability of flow microreactors can control various unstable and reactive species.…”

Flash functional group-tolerant biaryl-synthesis based on integration of lithiation, zincation and negishi coupling in flow

“…Frontiers in Chemical Engineering frontiersin.org the advantage of the flow microreactors, highly-selective chemical reactions have been achieved (Ashikari et al, 2019;Sugisawa et al, 2020;Ashikari et al, 2021). Based on this idea, we envisaged that aryl lithiums bearing electrophilic functionalities are generated by functional-group-tolerant halogen-lithium exchange reactions and, before they decompose, are converted to aryl zincs.…”
