Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

open access: yesAngewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...
