Variable coordination of amine functionalised N-heterocyclic carbene ligands to Ru, Rh and Rr: C-H and N-H activation and catalytic transfer hydrogenation [PDF]

, 2011
Chelating amine and amido complexes of late transition metals are highly valuable bifunctional catalysts in organic synthesis, but complexes of bidentate amine–NHC and amido–NHC ligands are scarce.

NEW ENTRY TO PIANO -STOOL ELECTRON RICH (PENTAMETHYL CYCLOPENTADIENYL) IRON COMPLEXES

Boletín de la Sociedad Chilena de Química, 2002
Se presenta una nueva ruta de sintesis para compuestos complejos pentametilociclopentadienilo-hierro(II) usando como precursor el dimero [Cp*Fe(CO)2]2. La reaccion de este dimero con I2 in CH2Cl2, produce el compuesto Cp*Fe(CO)2I el cual a su vez reacciona con bis(difenifosfinoetano) en tolueno para dar el complejo Cp*Fe(dppe)I. La reaccion de este con

Cytotoxicity of ruthenium(II) piano-stool complexes with imidazole-based PN ligands [PDF]

Journal of Organometallic Chemistry, 2012
Abstract A series of p-cymene ruthenium(II) complexes with imidazol-2-yl phosphines as PN ligands was prepared. Depending on the number of imidazolyl substituents in the ligands Ph3−nP(im)n {1–3: n = 1–3, im = imidazol-2-yl (a), 1-methylimidazol-2-yl (b)} different coordination modes were observed: κP, κ2N,N or κ3N,N,N.
