Highly chemo- and regioselective semihydrogenation of alkynes is significant challenging for the synthesis functionalized alkenes. Here, a sequential self-template method used to synthesize amorphous palladium sulfide nanocapsules (PdSx ANCs), which enables electrocatalytic terminal in H2O with excellent tolerance easily reducible groups (e.g., C–I/Br/Cl, C═O) metal center deactivating skeletons quinolyl, carboxyl, nitrile). Mechanistic studies demonstrate that specific σ-alkynyl adsorption via carbon negligible alkene on isolated Pd2+ sites ensure successful various alkenes outstanding time-irrelevant selectivity wide potential range. The key hydrogen radical intermediates are validated by electron paramagnetic resonance high-resolution mass spectrometry. Gram-scale 4-bromostyrene expedient preparation deuterated precursors drugs D2O show promising applications. Impressively, PdSx ANCs can be applied prevailing thermocatalytic alkyne using H2.

To date the majority of diene carboxylation processes afford α,δ-dicarboxylated product, selective mono-carboxylation dienes is a significant challenge and major product reported under transition metal catalysis arises from at α-carbon. Herein we report new electrosynthetic approach, that does not rely on sacrificial electrode, method allows unprecedented direct access to carboxylic acids derived δ-position. In addition, α,δ-dicarboxylic acid or α,δ-reduced alkene can be easily accessed by simple modification reaction conditions.
