Original Reactivity of ?-Diazo-?- ketoesters Catalyzed by CpRu Complexes
CHIMIA, 2014 Using ?-diazo-?-ketoesters as reagents and combinations of CpRu fragments and diimine ligands as catalysts, a series of original transformations have been obtained that can be rationalized by the formation of metal carbenes and metal-bound ylide

Enzyme–MOF Composites: Quantitative Benchmarking and Evaluation of Biocatalyst Performance
Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.Rigorous evaluation of enzyme@MOF composites requires quantitative benchmarking. This study illustrates this approach by applying and comparing enzyme‐loading and activity‐assessment strategies for two structurally and functionally distinct enzymes, phenolic acid decarboxylase, and cytochrome c.

Hydrogen Atom Transfer: An Intramolecular Main‐Group Metal‐Ligand Cooperative Biradical Pathway
Chinese Journal of Chemistry, Volume 44, Issue 13, Page 2121-2127, 1 July 2026.The molecular system consisting of a main‐group metal and a redox‐active ligand, ((2,6‐iPr2C6H3)NC(Me))2AlCl(THF), has been shown to react with azides and diazomethanes, yielding products through both a biradical intermediate and a hydrogen atom transfer process.

Isoxazolium N-ylides and 1-oxa-5-azahexa-1,3,5-trienes on the way from isoxazoles to 2H-1,3-oxazines
Beilstein Journal of Organic Chemistry, 2014 Theoretical and experimental studies of the reaction of isoxazoles with diazo compounds show that the formation of 2H-1,3-oxazines proceeds via the formation of (3Z)-1-oxa-5-azahexa-1,3,5-trienes which undergo a 6π-cyclization.
