In Situ Phase Transition and Cu Doping Synergistically Regulate Perovskite Z‐Scheme Heterojunction for Photocatalytic CO2 Reduction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel in situ synthesis strategy is proposed for fabricating Cu‐CsPbBr3/Cu‐CsPb2Br5 heterojunction materials, with dual optimization of structure and composition expanding the CO2 adsorption/activation area and enhancing intrinsic catalytic activity.

On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

European Journal of Organic Chemistry, EarlyView.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

Stereoselective Synthesis of Glycomimetic Amines From Biomass‐Derived Cyrene

European Journal of Organic Chemistry, EarlyView.
2,3,4‐Trideoxy‐2‐mannosamines, including the unsubstituted one, are accessible as the only endo diastereoisomers by reductive amination of the green solvent Cyrene, derived from pyrolysis of cellulose containing waste biomass. The products are useful chiral synthetic intermediate to nitrogenated glycomimetics.

Emerging Trends in Organic Photoreactions Utilizing Disulfides

European Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Preparation of α‐Mono‐Fluoromethyl Silanes via Nucleophilic Displacement on Chlorosilanes With LiCH2F

European Journal of Organic Chemistry, EarlyView.
The SiCl bond acts as a versatile platform for undergoing a formal nucleophilic substitution promoted by LiCH2F en route to extremely rare α‐monofluoromethyl‐silanes. Though surprising – when compared with well‐established poly‐fluoromethyl silanes (e.g., Ruppert‐Prakash reagent, TMSCF3) – α‐mono‐fluoromethyl silanes are underrepresented motifs in ...

Hofmann Degradation of Asparagine and Glutamine as an Efficient Approach for the Synthesis of Derivatized Lysine Homologs

European Journal of Organic Chemistry, EarlyView.
A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.
