Abstract:A series of Ru complexes stabilized with the pentapyridyl ligand PyMe (PyMe = 2,6-bis(1,1-bis(2-pyridyl)ethyl)pyridine) and with an axial X ligand (X = Cl, HO, N, MeCN) were prepared and characterized in the solid state and in non-aqueous solution. The cyclic voltammograms of these complexes in MeCN reflect a reversible substitution of the axial X ligand with MeCN. Irreversible ligand substitution of [(PyMe)RuN] is also observed in propylene carbonate, but only at oxidizing potentials that decompose the azide … Show more
The metastable purple [(Py5Me2)RuIII(N3)]2+ species undergoes a reaction with PPh3 at room temperature to form the RuII phosphinimine complex [(Py5Me2)RuII(N(H)PPh3)]2+ and free [H2NPPh3]+ observed in a combined 23% conversion. Mechanistic...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
