Abstract Asymmetric hydrogenation of olefins is one the most powerful asymmetric transformations in molecular synthesis. Although several privileged catalyst scaffolds are available, development for still a time‐ and resource‐consuming process due to lack predictive design strategy. Targeting data‐driven catalysis, we herein report standardized database that contains detailed information over 12000 literature hydrogenations olefins. This provides valuable platform machine learning applications catalysis. Based on this database, developed hierarchical approach achieve leaning model using only dozens enantioselectivity data with target olefin, which offers useful solution few‐shot problem will facilitate reaction optimization new olefin substrate catalysis screening.

Industrial manufacturing of ethylene chlorohydrin (ECH) critically requires excess corrosive hydrochloric acid or hypochlorous with dealing massive by-products and wastes. Here we report a green efficient electrosynthesis ECH from oxide (EO) NaCl over NiFe2 O4 nanosheet anode. Theoretical results suggest that EO Cl preferentially adsorb on Fe Ni sites, respectively, collaboratively promoting the synthesis. A radical-mediated ring-opening process is proposed confirmed, key carbon radical species are identified by high-resolution mass spectrometry. This strategy can enable scalable 185.1 mmol in 1 h 92.5 % yield at 55 mA cm-2 current density. Furthermore, series other chloro- bromoethanols good to high yields paired synthesis 4-amino-3,6-dichloropyridine-2-carboxylicacid via respectively loading unloading achieved, showing promising potential this strategy.

Catalytic systems using a small amount of organic photosensitizer for the activation an inorganic (on-demand ligand-free) nickel(II) salt represent cost-effective method cross-coupling reactions, while C(sp2 )-O bond formation remains less developed. Herein, we report strategy synthesis phenols with and photosensitizer, which was identified via investigation into catalytic activity 60 photosensitizers consisting various electron donor acceptor moieties. To examine effect multiple intractable parameters on photosensitizers, machine-learning (ML) models were developed, wherein embedded descriptors representing their physical structural properties, obtained from DFT calculations RDKit, respectively. The study clarified that integrating both DFT- RDKit-derived in ML balances higher "precision" "recall" across wide range search space relative to only one two descriptor sets.
