M. A. Khanfar, I. Warad and M. A. AlDamen

In the title compound, [RuCl₂(C₅H₁₄N₂)(C₁₈H₁₅P)₂], the Ru^II atom is six-coordinated, forming a slightly distorted octahedral geometry, with two chloride ions in an axial arrangement, and two P atoms of two triphenylphosphane and two chelating N atoms of the bidentate 2,2-dimethylpropane-1,3-diamine ligand located in the equatorial plane. The average Ru-P, Ru-N and Ru-Cl bond lengths are 2.325 (18), 2.1845 (7) and 2.4123 (12) Å, respectively.

Comment top

One of the important transformations in the organic synthesis is the reduction of ketones to secondary alcohol (Noyori, 1994). The enantioselective hydrogenation of prochiral carbonyl compounds to chiral alcohols is among the most valuable method in organic chemistry (Drozdzak et al., 2005; Lindner et al., 2005). Furthermore, stereo-, regio- and enantioselective ruthenium-catalysis lies at the heart of current developments in pharmaceutical, agrochemical and similar industries (Noyori, 2003; Clarke, 2002). Recently Noyori et al. (Ohkuma et al., 2002; Noyori & Ohkuma, 2001) discovered a ruthenium(II) complex system containing diphosphine and 1,2-diamine ligands which, in the presence of a base and 2-propanol, proved to be excellent catalysts (regarding efficiency, enantioselectivity, and flexibility) for the hydrogenation of ketones under mild conditions (Lindner et al., 2005; Noyori & Ohkuma, 2001). The title complex is crystallized as free solvated trans-dichloro-cis-bis(triphenylphosphane) isomer with approximate C_2v symmetry. The ruthenium atom is coordinated with two chlorine species in trans form, one diamine co-ligand via the nitrogen atoms and two triphenylphosphane ligands via the phosphorus atoms in cis forms. The complex exhibits distorted octahedron geometry around the ruthenium center atom with two Ru–N distances of 2.183 (3)Å and 2.185 (3) Å, two Ru–Cl distances of 2.4114 (8)Å and 2.4130 (8)Å and two Ru–P distances equal 2.3120 (8)Å and 2.3370 (8) Å. The diamine and phosphine ligands are practically planar. The coordination angle of the diamine chelate ring results in distinctly N–Ru–N angle of 82.35 (11)° departs from ideal value by up to approximately 7.6°, due to the six-membered ring chelating nature of 1,3-propanediamine ligand, while the P–Ru–P angle is equal 98.55 (3)°. The dichloro ligands are bent away from their axial positions toward the diamine ligand forming Cl–Ru–Cl angle of 166.32 (3)°, resonating to the steric effect of the phenyls in the phosphine ligands. In the crystal structure there are a number of RuCl···HN contacts smaller than 3.0 Å, indicating the presence of unconventional intra-hydrogen bonds (Doucet et al., 1998; Warad et al., 2006).

Experimental top

All the reactions were performed using Schlenk-type flask under argon and standard high vacuum-line techniques. Solvents were of analytical grade and distilled under argon. The title compound was prepared starting from trans-RuCl₂(PPh₃)₃ in a similar procedure described previously (Lindner et al., 2003b). Mixing of 2,2-dimethylpropane-1,3-diamine (0.059 ml, 0.49 mmol) in dichloromethane (10 ml) dropwise with trans-RuCl₂(PPh₃)₃ (0.454 mmol) dissolved in the same solvent (15 ml). The reaction mixture was stirred at room temperature for 2 h. The solvent was removed in vacuo. Then the residue was washed well with hexane then diethylether and dried, to yield 310 mg (90%) of yellow powder. The recrystallization was performed by slow diffusion of diethylether into a solution of the complex in dichloromethane to yield orange-brown-plated crystals. 1H NMR (CD₂Cl₂): δ (p.p.m.) 0.79 (s, 6H, C(CH₃)₂), 2.57 (m, 4H, NCH₂), 3.12 (br, s, 4H, NH₂), 7.2–7.7 (m, 20H, C₆H₅). ³¹P{1H} NMR (CD₂Cl₂):δ (p.p.m.) 46.02 (s). ₁₃C{¹H} NMR (CD₂Cl₂): δ (p.p.m.) 25.3 (s, C(CH₃)₂), 34.2 (s, C(CH₃)₂), 49.2 (s, CH₂N), 127.7 (t, N = 4.04 Hz, m-C₆H₅), 129.3 (s, p-C₆H₅), 135.4 (t, N=7.42 Hz,o-C₆H₅), 135.8 (d, N = 18.8 Hz, 1-C₆H₅).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
