Mechanochemical Hydrodeoxygenations

European Journal of Organic Chemistry, EarlyView.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using

Design and Synthesis of Lactose‐Derived Ligands and Their Application in Asymmetric Friedel–Crafts Alkylation

European Journal of Organic Chemistry, EarlyView.
This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

Nickel‐Catalyzed Three‐Component Coupling Reactions of Iodobenzenes, an Isocyanide, and a Disilathiane: Access to Cyclic Thioimidates and Secondary Thioamides

European Journal of Organic Chemistry, EarlyView.
The one‐pot synthesis of 3‐benzylidenbenzo[c]thiophen‐1‐amines was achieved through the nickel‐catalyzed three‐component coupling reaction of 1‐ethynyl‐2‐iodobenzenes, tert‐butyl isocyanide, and hexamethyldisilathiane. This procedure is applicable to the preparation of secondary thioamides using aryl iodides.

Antibacterial Hydrogel Dressing With Ca2+‐Dependent Hyaluronidase Responsiveness for Accelerating Wound Healing via On‐Demand Release of AIE Photosensitizers

Exploration, EarlyView.
This study innovates a Ca2+‐responsive hydrogel dressing that releases AIE photosensitizers on‐demand. Low Ca2+ enhances bacterial hyaluronidase (HAase) activity, degrading hyaluronic acid dressing to trigger antibacterial ROS release, while high Ca2+ inhibits HAase, preventing overdosing.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Strengthened inter‐chain π–π contacts in amorphous diketopyrrolopyrrole polymers for robust flexible organic thin‐film transistors

FlexMat, EarlyView.
Vinylene‐linked DPP polymers with expanded thiophene donors achieve strengthened interchain π‐π stacking in near‐amorphous films, enabling high charge mobility and outstanding mechanical stability for flexible organic thin‐film transistors. Abstract Flexible organic thin‐film transistors (OTFTs) based on multi‐vinylene‐linked diketopyrrolopyrrole (DPP)
