Synthesis, Molecular Structure and Catalytic Activity of Six‐Coordinate Chloro(hydrido)‐ and Dihydridoruthenium(II) and ‐osmium(II) Complexes with the Chiral Ligands PiPr₂NH(Me)Ph, (S,S)‐Chiraphos and (S,S,)‐Diop

Synthesis of chiral heterobimetallic tris(phosphinoamide) Zr/Co complexes

“…Treatment of (R)-α-methylbenzylamine with ClP i Pr in the presence of external base cleanly produced the desired phosphinoamine (R-PhCH 3 CH)NHP i Pr 2 (1) in 93% yield. The physical properties as well as the 1 H and 31 P NMR spectra of 1 exactly matched those reported in the literature for the opposite enantiomer [45].…”

Hydrido‐Osmium(II), ‐Osmium(IV) and‐Osmium(VI) Complexes with Functionalized Phosphanes as Ligands

“…[3] Moreover, under a hydrogen atmosphere, complex 1 also catalyzes the reduction of cyclohexene, 1,3-and 1,4-cyclohexadiene, styrene and phenyl-and diphenylacetylene. [4,5] After we observed that the PiPr 3 ligands of 1 can easily be replaced by chiral mono-and bisphosphanes such as PiPr 2 NHCH(Me)Ph, (S,S)-Chiraphos and (S,S)-Diop, [6] we became interested to find out whether a similar substitution reaction would also occur with hemilabile, potentially chelating phosphanes. We note that the chemistry of a manifold of osmium and ruthenium compounds with phosphane ethers, phosphane esters and phosphaneamines as ligands has recently been investigated in our laboratory as well as by others.…”

Synthesis, characterization, reactivity and theoretical studies of ruthenium carbonyl complexes containing ortho-substituted triphenyl phosphanes

“…Although ruthenium-phosphanes are well-known systems, they are still of interest. Studies on new ruthenium complexes [19] as well as mechanistic reports [20,21] other applications, for example in the development of sensors [22] or as a tool in supramolecular chemistry [23].…”
