Ferrocenyl phosphine thioether ligands (PS), not containing deprotonatable functions, efficiently support the iridium catalyzed ketone hydrogenation in combination with a strong base cocatalyst. Use of an internal ([Ir(OMe)(COD)]2 place [IrCl(COD)]2) is sufficient to ensure activity and still necessary, suggesting that active catalyst anionic hydride complex. Computational investigations include solvent effects demonstrate thermodynamically accessible generation tetrahydrido complex...
Highly convergent synthesis of bis(triazolylphosphane oxides) by a tandem copper-mediated Huisgen reaction–oxidative coupling.
Reaction of RhCl(PR3)n (R = Me (n 4), Et 3)) and RhCl(CO)(PEt3)2 with (trimethylsilyl)diazomethyl lithium at −78 °C in ether yields the three complexes Rh[C(N2)SiMe3](PEt3)3 (1), Rh[C(N2)SiMe3](PMe3)4 (2), Rh[C(N2)SiMe3](CO)(PEt3)2 (3). 2 could not be isolated as a solid room temperature but 1 was precipitated red crystals that were stable enough to handled under argon. X-ray work on reveals tetrahedrally distorted square-planar geometry planar ligand roughly perpendicular P3RhC coordination...

A series of ferrocenyl-phosphine ligands has been used to stabilize small rhodium nanoparticles that are active in the catalytic hydrogenation styrene.
Abstract While current research on Ni-catalyzed olefin polymerization predominantly focuses ligand design, ion-pair interactions remain largely unexplored. We report the development of air-stable carbyl iminopyridyl Ni II precatalysts to enable an investigation inner- and outersphere ion-pairs. The use innersphere organoboron counterions allows complexes access higher molecular weight homo/co-polymers regulate density distribution polyethylene branches. Moreover, implementing a phenyl group...
A series of arene ruthenium iminophosphonamide complexes, [(Arene)RuCl{R2P(NR')2}] (1), bearing various arenes and R,R' substituents on the NPN ligand have been investigated as precatalysts in acetophenone transfer hydrogenation basic base-free isopropanol. The results clearly demonstrate presence two distinct reaction mechanisms, which are controlled by basicity N-atoms. Complexes 1 both R' aryl groups only active once neutral hydride complex [(Arene)RuH{R2P(NR')2}] (2) is generated...
Interactions of Cu2+, Zn2+, and Pd2+ ions with the antitumor compound mitomycin C (MMC) have been investigated by UV−vis, circular dichroism, 13C NMR spectroscopy. While Zn2+ Cu2+ neither interacted MMC nor catalyzed formation mitosenes, induced strong spectral modifications, suggesting a major complex, in which acted as bidentate ligand through N(1) N(4) atoms. The coordination mode this complex was solvent dependent: MeOH, NH2 carbamate function also involved third site whereas, H2O,...
In this account the authors' latest results in C-C coupling catalysis are reviewed. First, an efficient catalytic system for Kumada-Tamao-Corriu reaction based on NHC-phosphine (NHC = N-heterocyclic carbene) nickel complexes is presented. Then use of palladium chiral ferrocenyl NHC-phosphines asymmetric Suzuki-Miyaura reported. High activities and moderate enantioselectivities (ee up to 46%) were obtained. Chiral phosphine-ethers also tested yielding good 37%). Finally, original synthesis a...
