Ruthenium Dihydride Complexes: NMR Studies of Intramolecular Isomerization and Fluxionality Including the Detection of Minor Isomers by Parahydrogen-Induced Polarization
Autor: Danièle Schott, Martin G. Partridge, Simon B. Duckett, Roger J. Mawby, John P. Lowe, Christopher J. Sleigh
Publikováno v: Inorganic Chemistry. 41:2960-2970
NMR studies reveal that complexes Ru(CO)(2)(H)(2)L(2) (L = PMe(3), PMe(2)Ph, and AsMe(2)Ph) can have three geometries, ccc, cct-L, and cct-CO, with equilibrium ratios that are highly dependent on the electronic properties of L; the cct-L form is favo
