Organic electrochemistry has recently witnessed a renaissance in research as green and cost-efficient method for activating small molecules. Although some of the critical challenges batch electrosynthesis remain, flow can overcome several issues arising from electroorganic systems, such mass transfer, ohmic drop, selectivity. The combination technology with affords practitioners very precise control over reaction conditions, thereby enhancing reproducibility electrochemical processes. use gases chemical reactions synthesis value-added fine chemicals is great significance. This review summarizes recent advances biphasic (gas-liquid) organic synthesis. We summarise examples selective hydrocarbon oxidations using oxygen gas an reactor.

Abstract A widely used method to obtain tetrazoles is through the azide and nitrile [3+2] cycloaddition. However, this process often involves using non‐recyclable transition metals or Lewis acid catalysts stoichiometric amounts of oxidants additives, which reduces atom efficiency. We have discovered a convergent paired electrochemical reaction perform cycloaddition reaction, without need for metal oxidants. This tetrazolation strategy uses azidotrimethylsilane (TMSN 3 ) N ‐heterocycles in an undivided cell at constant current. use mixture CH CN equivalent H 2 O as co‐solvent room temperature. It crucial produce amount active hydroxyl ions cathodic reduction water. Cyclic voltammetry (CV) studies control experiments confirm that specific electrode electron transfer process, eliminating mediator shuttle electrons. metal‐ oxidant‐free highly compatible with different functional groups produces products moderate good yields. successfully tetrazolated bioactive compounds late stage, scaled up batches efficiently, synthesized free amino‐containing via denitrogenation tetrazoles.
