Stereospecific Transition‐Metal‐Free Alkylation of Chiral Non‐Racemic Secondary Tosylates with Cyanohydrins: Convenient Access to Enantiomerically Enriched α‐Tertiary Ketones

Angewandte Chemie, EarlyView.
A stereospecific, transition‐metal‐free SN2 alkylation of cyanohydrins with chiral non‐racemic secondary tosylates is reported, providing efficient access to enantioenriched α‐tertiary ketones. The method exhibits broad substrate scope, operational simplicity, and excellent stereospecificity, including stereoconvergent reactions of E/Z mixtures of ...

Core‐Shell: Resolving the Dilemma of Hard Carbon Anodes by Sealing Nanoporous Particles With Semi‐Permeable Coatings

Angewandte Chemie International Edition, EarlyView.
A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%
