Synthesis, characterization, and catalytic behaviour of a dimeric ruthenium(II) methoxydiphenylphosphane complex

The dual role of cis-[RuCl2(dmso)4] in the synthesis of new water-soluble Ru(II)–phosphane complexes and in the catalysis of redox isomerization of allylic alcohols in aqueous–organic biphasic systems

“…[8,9] Earlier cis-[RuCl2(dmso)4], 1 was used as precursor for the synthesis of Ru(II)-complexes with aryl, sulfonated aryl, and cyclohexyl phosphanes, both in aqueous and in non-aqueous media. [8,[10][11][12][13][14] In addition, several ligands with N-and O-donor atoms were studied in substitution reactions of both isomers of [RuCl2(dmso)4]. [15] This was -in part-motivated by the expected biological effects of the products.…”

Preparation and crystal structure of [Ru2(μ-Cl)3(P(CH2OH)3)6]Cl

“…1) contains binuclear cations [Ru 2 (μ Cl) 3 (P(CH 2 OH) 3 ) 6 ] + and Clanions. The binuclear complex has a {P 3 Ru(μ Cl) 3 RuP 3 } + core built of two confacial octahedra with a nonbonding Ru⋅⋅⋅Ru distance of 3.350 Å, typical of this class of Ru(II) complexes [17][18][19][20][21][22][23][24][25][26][27]. Each Ru atom has an octahedral environment and is coordinated with three chlorine atoms and three phosphorous atoms of the THP ligands.…”

“…The valence angles Cl-Ru-Cl and P-Ru-P are close to 80° and 95°-97°, respectively (Table 3). This geometry is unexceptional for the {Ru 2 (μ Cl) 3 RuP 6 } + core [17][18][19][20][21][22][23][24][25][26][27]. The CH 2 OH groups of all THP molecules in the crystal structure of I are disordered over three posi tions.…”

Novel Phosphinite−Ruthenium(II) Complexes Covalently Bound on Silica: Synthesis, Characterization, and Catalytic Behavior versus Oxidation Reactions of Alcohols into Aldehydes

“…In this paper, we describe our attempts to construct heterogeneous ruthenium catalysts which would operate as if they were in solution. In preliminary experiments,14a we have already selected phosphinite derivatives as metal ligands because they appear to be more stable toward self-oxidation than the traditional phosphine ligands. The selected support was silica, a material chemically stable to oxidation, which can be easily derivatized by standard reactions .…”
