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.

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

European Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones

European Journal of Organic Chemistry, EarlyView.
Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.

Efficient Synthesis of Cannabinoid Acids

European Journal of Organic Chemistry, EarlyView.
In this study, an alternative synthesis of cannabinoid acids was developed based on an O→C acyl rearrangement. Specifically, this strategy involved regioselective bromination followed by halogen–lithium exchange and intramolecular nucleophilic addition, which led to successful carboxylation.

Fluorinated Iminosugar Glycomimetics: Synthesis and Activity as GCase Ligands

European Journal of Organic Chemistry, EarlyView.
DAST‐mediated deoxyfluorination of suitably functionalized piperidines provided regio‐ and stereoselective access to fluorinated piperidine and pyrrolidine glycomimetics, the latter arising from an unusual ring‐contraction process. Fluorination generally enhanced β‐glucocerebrosidase (GCase) inhibitory potency, but lost PC activity toward L444P/L444P ...

Photocatalysis‐Triggered Click Reactions and Applications

European Journal of Organic Chemistry, EarlyView.
Photoclick chemistry offers broad applications ranging from materials science to bioconjugation, with precise spatiotemporal control over click reactions. Initially limited to UV activation, recent advances have extended photoclick processes to the visible and NIR regions thanks to the photocatalysis.

Investigation of α‐Silylalcohols as Chiral Umpolung Carbanion Surrogates Through Stereospecific 1,2‐Brook Rearrangement

European Journal of Organic Chemistry, EarlyView.
Deprotonation of chiral α‐silyl secondary alcohols leads to masked polarity‐reversed chiral carbanions through stereospecific 1,2‐Brook rearrangement. In situ trapping with Weinreb amide electrophiles affords α‐hydroxyketones with moderate to excellent enantiospecificity (es).
