Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.Merging silylium‐ion and palladium catalysis provides a mechanistically distinct route to allylsilanes by formal C–H/Si–H metathesis. Using allylsilanes as silicon proelectrophiles, various allylarenes undergo migrative silylation, selectively yielding (E)‐allylsilanes.

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.Cyclopropanols undergo palladium‐catalyzed, zinc‐mediated allylation with allyl acetates: the ring opens transiently to an enolized homoenolate, is intercepted by π‐allylpalladium, and recloses to furnish β‐allylated cyclopropanols. This formal “allylic cyclopropylation” broadens the reaction space for ring‐retentive functionalization of cyclopropanols.

Ruthenium-Catalyzed Ring-Opening and Ring-Closing Enyne Metathesis
, 2016 When a CH2Cl2 solution of an enyne containing the cycloalkene moiety was stirred in the presence of ruthenium−carbene complex (10 mol %) at room temperature under ethylene gas (1 atm), ring-opening and ring-closing metathesis occurred to afford cyclized ...

Aggregate, Volume 7, Issue 11, November 2026.Conformational fixation of donor–acceptor merocyanines modulates excited‐state relaxation and fluorescence. Viscosity‐ and aggregation‐dependent emission, combined with TDDFT calculations, reveal a strongly twisted charge‐separated state in solution and a torsionally constrained emissive state in rigid environments, establishing a unified picture of ...

Ring-Closing Metathesis on Commercial Scale: Synthesis of HCV Protease Inhibitor Simeprevir
, 2019 The key macrocyclization step in the synthesis of simeprevir, a hepatitis C virus (HCV) antiviral drug, was studied. N-Boc substitution on the diene precursor changes the site of insertion of the metathesis catalyst and, consequently, the kinetic model ...
