Abstract Oximes are important intermediates for various chemicals synthesis such as pharmaceuticals, among which one vital precursor producing neurological disease, antimicrobial and anticancer agents is piperidone oxime (PDO). Compared with conventional thermocatalytic method, it's more attractive to synthesize PDO via green electrocatalytic technology especially utilizing waste nitrogen oxides gas source. However, there great challenges in catalyst design high‐efficiency electrosynthetic due the low electron transport rate multiple competing reactions. Herein, we propose an interfacial coordination strategy based on metal–organic frameworks (MOF) electrocatalyst first time promote electrosynthesis, by building Zn−O bridges between graphite felt (GF) zeolitic imidazolate framework (ZIF‐7/CGF). Specially, ZIF‐7/CGF delivers a Faraday efficiency (FE) of 75.9 % yield up 73.1 1‐methyl‐4‐piperidone oxime, far superior without (a FE 10.7 10.3 %). In‐depth mechanism study shows that introducing can transfer induce Zn sites transforming into distorted tetrahedron (Zn‐N 3 O) mode, benefits adsorption conversion. The developed presents wide universalities towards oximes electrosynthesis adapts other MOF materials (ZIF‐8, ZIF‐4). This work provides new insights organic upgrading cycle through rational surficial coordinated electrocatalysts.

The electrochemical coupling reaction of beta-nitrostyrene and 4-chloro-beta-nitrostyrene was reported. This is the first report on beta-nitrostyrenes. Moreover, processes were performed using simplest conditions; constant current (simpler than potential), simple undivided cell, employing non-expensive graphite still electrodes, a green solvent (ethanol), performing at room temperature. First, various cyclic voltammetry experiments, effects potential scan rate pH behavior reactant investigated. Then, conditions such as pH, solvent, type density optimized by examination yield product. pH=6, ethanol steel sheets cathode, rod anode, density=0.97 mA/cm2 (30 mA current). coulometry, number exchanged electrons in this process calculated to help find possible mechanism. After completion reactions, products identified mass spectrometry, FT-IR, NMR methods. It found that only more thermodynamically stable meso configurations are produced, which makes diastereoselective. plausible mechanism, obeyed from EC proposed for reaction, including two-electron transfer reaction.
