Testing Differently Substituted Quinoxaline‐2,3‐Dithiolate Ligands in Z‐Stereoretentive Olefin Metathesis Leading to Pheromone of Rice Yellow Stem Borer (Scirpophaga incertulas)

open access: yesEuropean Journal of Lipid Science and Technology, Volume 127, Issue 7, July 2025.
A set of Z‐stereoretentive olefin metathesis catalysts was tested in the synthesis of a pheromone of rice yellow stem borer (Scirpophaga incertulas)—one of the major rice pests in Asia. ABSTRACT Stereoselective olefin metathesis offers access to geometrically well‐defined C–C double bonds and is considered a promising new method for transforming plant ...

A Very Readily Prepared Ligand for Rhodium Catalyzed Propene Hydroformylation

open access: yesChemistry – A European Journal, Volume 31, Issue 34, June 17, 2025.
Recent developments aimed at switching the selectivity of rhodium catalyzed hydroformylation from a linear‐selective to a branched selective reaction feature ligands that are relatively complicated to prepare. A new ligand, EasyDiPhos, can be made in just one synthetic step and gives unusually low n:iso ratios, i.e., favoring the branched aldehyde, iso‐

Synthesis of 16‐Electron RuHCl(CO)(PPh3)2 Catalyst Rendering Superior C═C Double Bond Isomerization Activity

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Coordinatively unsaturated ruthenium(II) hydride complex, RuHCl(CO)(PPh3), has been synthetized showing high efficiency in C═C isomerization of terminal alkenes at room temperature and low catalyst loadings. The double bond isomerization of alfa olefins plays a key role in converting plastic waste into propylene via isomerization metathesis (ISOMET ...

The development and application of new methods for the synthesis of organozinc carbenoids [PDF]

open access: yes, 1998
This thesis concerns the generation of organozinc carbenoids and their subsequent reactions, particularly with alkenes to generate cyclopropanes. The thesis is divided into three major sections. The first section comprises a review of the current methods

Artemisia dracunculus L. (tarragon): a critical review of its traditional use, chemical composition, pharmacology, and safety. [PDF]

open access: yes, 2011
Artemisia dracunculus L. (tarragon) has a long history of use as a spice and remedy. Two well-described "cultivars" (Russian and French) are used widely and differ in ploidy level, morphology, and chemistry.
