Ruthenium-Coordinated Spirolactams via Intramolecular Nucleophilic Addition to η⁶-Arene Metal Complexes

, 2016
Cyclohexadienyl ruthenium(II) complexes incorporating an azaspirocyclic ring system have been prepared from (η6-N-benzyl acetoacetamide)CpRu(II) precursors via an intramolecular nucleophilic aromatic addition/enolate trapping reaction sequence.

Revisiting ruthenium scorpionate chemistry: Reactivity of bis(3,5-dimethylpyrazol-1-yl)acetic acid toward organoruthenium(II) precursors

Acta Chimica Slovenica
The reactivity of the scorpionate ligand bis(3,5-dimethylpyrazol-1-yl)acetic acid (L1H) toward organoruthenium(II) precursors was investigated. Reactions of chlorido and bromido p-cymene ruthenium dimers afforded the corresponding complexes in which L1H

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

Recoveries of Ru(III) and Co(II) by Solvent Extraction and Ion Exchange from Tungsten Carbide-Cobalt Scrap through a HCl Leaching Solution

Metals, 2019
The addition of ruthenium to tungsten carbide-cobalt hard metals improves their mechanical properties. Since ruthenium is a platinum group metal, the recovery of ruthenium together with cobalt from the scrap of hard metals is of great importance.
