Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis
ChemSusChem, Volume 19, Issue 17, 14 September 2026.This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation
Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

Angewandte Chemie International Edition, Volume 65, Issue 36, 1 September 2026.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.
