The oxidation of benzyl alcohols is an important reaction in organic synthesis. Traditional methods for alcohol have not been widely utilized due to the use significant amounts precious metals and environmentally unfriendly reagents. In recent years, electrocatalytic has gained attention, particularly electrochemical anodic oxidation, which offers a sustainable alternative without need external oxidants or reducing agents. Here, copper monosubstituted phosphotungstate-based polyacrylate resins (Cu-LPOMs@PPAR) catalyst fabricated with immobilization recyclability using 3D printing technology that can be successfully applied benzaldehyde, achieving atom economy pollution. this protocol, we obtain benzaldehyde good yields excellent functional group toleration under metal-free oxidant-free conditions. This strategy could provide new avenue heterogeneous catalysts application enhancing efficiency selectivity processes.

Herein, we report a visible light-induced synthesis of sulfenamides via the oxidative coupling amines with thiols using O2 as an oxidant. The photoreaction was conducted under simple and mild conditions, without any photocatalysts, metals, or additives. Detailed mechanistic studies revealed that sulfur radical is generated through single-electron transfer from in situ-generated anion to light irradiation. This intermediate couples form disulfide, which subsequently undergoes aminolysis produce sulfenamides.

Comprehensive Summary The development of new strategy for environmentally friendly, cost‐effective and large‐scale electro‐synthesis anticancer drugs is highly desirable to replace high‐cost traditional methods realize high atomic economy. GW 610, an antitumor agent with potent selective activity against lung, colon, breast cancer cell lines in real medical treatment processes, has a market price ~10 7 USD/kg calls novel like reduce the cost. Here, first time, we design solid‐liquid‐gas three‐phase indirect electrolysis system based on kind microwave‐synthesized polyoxometalate‐based metal‐organic framework (MW‐POMOF) that can converse S–S bond substrates into valuable C–S products drug molecules ( e.g ., 610). Specifically, solid‐phase MW‐POMOF as heterogeneous redox mediator exhibits excellent electrocatalytic efficiency formation liquid‐phase (yields up 95%) coupling generation gas‐phase H 2 product (~402 μmol·g –1 ·h ), resulting interesting system. Remarkably, it enables kilo‐scale production (~1 kg batch experiment) 610 at one thousandth (from ~3200 USD/kg). This work may inaugurate avenue explore porous crystalline materials electrocatalysis field.
