Synthesis and unexpected reactivity of [Ru(η 6-cymene)Cl2(PPh2Cl)], leading to [Ru(η 6-cymene)Cl2(PPh2H)] and [Ru(η 6-cymene)Cl 2 (PPh2OH)] complexes

The reaction of [Ru(η 6-cymene)Cl2]2 and PPh2Cl in the ratio 1:2 gives a stable [Ru(η 6-cymene) Cl2(PPh2Cl)] complex. Attempts to make the cationic [Ru(η 6-cymene)Cl(PPh2Cl)2]Cl with excess PPh2Cl and higher temperatures led to adventitious hydrolysis and formation of [Ru(η 6-cymene)Cl2(PPh2OH)]. Attempts to make a phosphinite complex by reacting [Ru(η 6-cymene)Cl2]2 with PPh2Cl in the presence of an alcohol results in the reduction of PPh2Cl to give [Ru(η 6-cymene)Cl2(PPh2H)] and the expected phosphinite. The yield of the hydride complex is highest when the alcohol is 1-phenyl-ethane-1,2-diol. All three half-sandwich complexes are characterized by X-ray crystallography. Surprisingly, the conversion of chlorodiphenylphosphine to diphenylphosphine is mediated by 1-phenyl-ethane-1,2-diol even in the absence of the ruthenium half-sandwich precursor.

NOUVEAUX COMPLEXES HETEROBINUCLEAIRES A LIAISON RUTHENIUM-COBALT PONTEE PAR UN GROUPEMENT DIPHENYLPHOSPHIDO

The reaction of RuCl2(PPh2Cl)(p-cymene) with Co2(CO)8 in THF leads to the formation of the heterobimetallic RuCo(μ-PPh2)(CO)7 derivative, containing a diphenylphosphido-bridged Ru-Co bond.The ?-areneruthenium complex 6-C6H3CH(CH3)2>RuCO(μ-PPh2)(CO)4 is obtained in addition to RuCo(μ-PPh2)(CO)7 by treatment of RuCl2(PPh2H)(p-cymene) with Co2(CO)8.

Mild intramolecular P–C(sp3) bond cleavage in bridging diphosphine complexes of RuII RhIII and IrIII

Three new carboxylic acid functionalised diphosphines, R2PCH2N(Ar)CH2PR2 [CyL1 R = Cy, Ar = (1-CO2H)(3-OMe)C6H3, CyL2 R = Cy, Ar = (1-CO2H)(3-OH)C6H3 and PhL3 R = Ph, Ar = (1-CO2H)(5-OMe)C6H3] have been prepared from condensation of R2PCH2OH and the appropriate aromatic amine in MeOH, and isolated as colourless solids (for CyL1, CyL2) in good yield. Reaction of CyL1, CyL2, or PhL3, along with the previously reported diphosphines PhL1, PhL2, and PhL4, and [RuCl(μ-Cl)(η6-Me2CHC6H4Me)]2 in CH2Cl2 affords the P/P-bridging dinuclear ruthenium(II) complexes {RuCl2(η6-Me2CHC6H4Me)}2(μ-CyL1?PhL4) 1a?f as red/orange solids. Careful monitoring by 31P{1H} NMR spectroscopy of CDCl3 solutions of 1a?e revealed remarkably clean P?Csp3 bond cleavage to give RuII mononuclear species 2a?e and the known secondary phosphine complexes RuCl2(η6-Me2CHC6H4Me)(PCy2H) 3 and RuCl2(η6-Me2CHC6H4Me)(PPh2H) 4. Furthermore, facile P?Csp3 bond cleavage of PhL1 can be observed using the chloro-bridged dimers [IrCl(μ-Cl)(η5-C5Me5)]2 or [RhCl(μ-Cl)(η5-C5Me5)]2 instead. Deuterium labelling of CyL1, CyL1, PhL1, and PhL2 enabled the assignment of the methylene protons to be confirmed from 1H NMR spectroscopy. All new compounds have been characterised using a range of spectroscopic and analytical techniques. Single crystal X-ray structures have been determined for CyL1, 1d·3OEt2, 1f·2CDCl3·OEt2, 2b, 2c, 2d·CDCl3, 2e·0.5OEt2 and 6b·1.5CDCl3. The free phenolic group in CyL1, 1d·3OEt2, 1f·2CDCl3·OEt2, 2b and 2d·CDCl3 participates in intra- or intermolecular O?H···O hydrogen bonding.

The [RuCl2(η6-arene)]2 complex reacts with PPh2R (R=H, Py, CH2Py, CCPh, CCtBu and CCp-Tol) ligands in CH2Cl2 to give neutral P-coordinated ruthenium(II) complexes [RuC

Heteronuclear and heterovalent diphenylphosphido-bridged complexes of rhodium, iridium and ruthenium. Crystal structure of *1/2Et2O (COD = 1,5-cyclooctadiene)

Phosphido-bridged mixed-metal (Ru/Co) compounds via the reaction of (arene)RuCl2(PPh2X) (X = H, Cl) with Co2(CO)8: X-ray structure of RuCo2(μ-PPh2)2(μ-CO)(CO)7

A strategy for the synthesis of heterobi- and heterotrinuclear phosphido-bridged complexes via the reactions of the readily available η6-arene compounds (p-cymene)RuCl2(PPh2X) (X = H, Cl) with Co2(CO)8 is described. This route has afforded heterobinuclear (CO)4Ru(μ-PPh2)Co(CO)3 (3), (p-cymene)(CO)Ru(μ-PPh2)Co(CO)3 (7), small amounts of Ru2(μ-PPh2]2(CO)6 (4), and the heterotrinuclear clusters Ru2Co(μ-PPh2)(CO)10 (5) and RuCo2(μ-PPh2)2(CO)8 (6). These compounds have been characterized by microanalysis and mass, infrared, and NMR (1H, 13C, 31P) spectroscopy. Single crystals of RuCo2(μ-PPh2]2(CO)8 are monoclinic of space group P21/n with a = 12.714 (2) A?, b = 15.600 (3) A?, c = 17.246 (3) A?, β = 108.33 (1)°, and Z = 4. The structure was solved and refined by using 3610 unique, observed reflections measured on a Syntex P21 diffractometer to R and Rw values of 0.034 and 0.039. In the triangular cluster the trans axial PPh2 groups bridge the Ru-Co(1) and Co(1)-Co(2) edges with a semibridging CO group across the remaining Ru-Co bond.
