Peptide Thioester and Triazole Derivatives Through On‐Resin Dual‐Modification of Peptide Thiosulfonates

Angewandte Chemie International Edition, EarlyView.
An on‐resin dual‐modification strategy for peptides is presented, comprising S‐alkynylation of peptide thiosulfonates and regioselective iridium‐catalyzed azide–thioalkyne cycloaddition. This method reliably provides access to peptides with intricate non‐canonical modifications, being compatible with complex peptides, alkynes and azides.

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

Angewandte Chemie International Edition, EarlyView.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

Catalytic C–F Bond Activation at Room Temperature: Enolate Cross‐Couplings Enabled by [Pd(1‐MeNAP)TFA]2 and LiHMDS

Angewandte Chemie International Edition, EarlyView.
Catalysts generated from the trifluoroacetate‐bridged methylnaphthyl‐palladium dimer [Pd(1‐MeNAP)TFA]2 and biarylphosphine ligands in combination with the base LiHMDS promote α‐arylation reactions of various enolates with non‐activated aryl fluorides at room temperature.

Changing a Winning Team—Replacement of Brominated Flame Retardant and Antimony Trioxide in Acrylonitrile–Butadiene–Styrene

Journal of Applied Polymer Science, EarlyView.
This comprehensive study investigates reducing the amount of brominated flame retardant (Br) and/or antimony trioxide (ATO) in acrylonitrile–butadiene–styrene. Therefore, condensed‐phase flame‐retardant mechanisms are introduced into the flame‐inhibition system.

Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin

Journal of Applied Polymer Science, EarlyView.
The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting Tg,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior Tg of 135°C.
