Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Shedding Light on the Precatalytic Mixture of Pd(OAc)2 and Cooperating Bipyridone Ligands for the C─H Functionalization of Arenes

open access: yesChemCatChem, EarlyView.
The reactions of the common palladium precursors Pd(OAc)2 and PdCl2 and cooperating bipyridone ligands leads to well defined complexes which are general precatalysts for the direct C─H arylation of arenes, more active than Pd(OAc)2/ligand mixtures in nonpolar solvents.

Total Synthesis and Analysis of Phenolic Phytoprostanes, Oxidized Derivatives of Lipophenols

open access: yesChemistry – A European Journal, EarlyView.
The total synthesis of four hydroxytyrosol‐phytoprostanes (PhytoPs‐HT) was achieved in 20 steps, enabling their first identification as HT‐α‐linolenate oxidation products. This work revealed new oxidized derivatives of lipophenols via UHPLC‐MS/MS analysis, offering a strategy to trace HT‐derived compounds in complex matrices, aiding food and biomedical
