Ruthenium-Catalyzed Propargylation of Aromatic Compounds with Propargylic Alcohols

, 2016
A novel ruthenium-catalyzed propargylation of aromatic compounds with propargylic alcohols has been found to afford the corresponding propargylated aromatic products in good yields with complete regioselectivity.

Metalloglycomics of tris(2,2′-bipyridyl) cobalt and ruthenium compounds

, 2022
Metal complexes studied to date under the framework of metalloglycomics belong to the M-NH3 general motif (polynuclear platinum compounds; Werner's complex), acting mainly as cationic hydrogen bonding species toward glycosaminoglycans (GAGs), an ...

Ruthenium-Catalyzed Direct Asymmetric Reductive Amination for the Synthesis of a Chiral Primary Amine Intermediate En Route to a PDE2A Inhibitor, TAK-915

, 2023
Here, we report a novel, efficient ruthenium-catalyzed direct asymmetric reductive amination of an α-alkoxy ketone, a structural motif for which it is more challenging to implement such a transformation than 1,3-dicarbonyl compounds.

A Staining Protocol for Identifying Secondary Compounds in Myrtaceae

Applications in Plant Sciences, 2014
Premise of the study: Here we propose a staining protocol using toluidine blue (TBO) and ruthenium red to reliably identify secondary compounds in the leaves of some species of Myrtaceae.

Recent Investigations on Thiocyanate-Free Ruthenium(II) 2,2′-Bipyridyl Complexes for Dye-Sensitized Solar Cells

Molecules, 2021
Three decades ago, dye-sensitized solar cells (DSSCs) emerged as a method for harnessing the energy of the sun and for converting it into electricity. Since then, a lot of work has been devoted to create better global photovoltaic efficiencies and long ...

Modification of Polyhedral Oligomeric Silsesquioxanes (POSS) Molecules by Ruthenium Catalyzed Cross Metathesis

Molecules, 2018
The scope of ruthenium (Ru)-catalyzed cross metathesis (CM) of allyl-decorated polyhedral oligomeric silsesquioxanes (POSS) was explored. A variety of different commercial and non-commercial ruthenium complexes were tested to determine that the nitro ...
