A scalable flow electrochemical platform achieves up to 9.2 g/h productivity at a 100 g scale using an innovative three-electrode reactor design. Dual-sided cathodes enable 16 parallel channels across eight modules, maintaining 1 min residence time without reoptimization. The methodology processes diverse α,β-unsaturated carbonyl substrates (chalcones, heterocyclic enones, esters, ketones, carboxylic acids), explored 18 examples with broad functional group tolerance. The average productivity improvement across the substrates is 75-fold than the batch method with consistent performance from gram to pilot scale, establishing a cost-effective pathway for the electrochemical reduction reaction.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Preparation of Aldehydes and Ketones from Carboxylic Acid Derivatives
Carboxylic acid derivatives like acid chlorides and esters are more easily reducible than the corresponding acids. The derivatives reduce in the presence of mild reducing agents to give aldehydes. Aldehydes can also be prepared by Rosenmund reduction, that is, the reduction of acid...
Preparation of Aldehydes and Ketones from Nitriles and Carboxylic Acids
Reducing carboxylic acid derivatives like acyl chlorides (RCOCl), esters (RCO2R′), and nitriles (RCN) using milder aluminum hydride agents like lithium tri-tert-butoxyaluminum hydride [LiAlH(O-t-Bu)3] and diisobutylaluminum hydride [DIBAL-H] allows...

Preparation of Amines: Reduction of Oximes and Nitro Compounds
Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...
