Chiral pyridylamino-ruthenium(ii) complexes: Synthesis, structure and catalytic properties in Diels-Alder reactions

Half-sandwich complexes [(eta6-arene)RuCl(pyam)][SbF 6] (pyam = Ln = N-(2-pyridylmethyl)-(R)-1-phenylethylamine (L1), N-(2-pyridylmethyl)-(R)-1-naphthylethylamine (L2), N-(2-quinolylmethyl)-(R)-1-naphthylethylamine (L3), N-(2-pyridylmethyl)-(R)-1-cyclohexylethylamine (L4), N-(2-pyridylmethyl)-(1R,2S,4R)-1-bornylamine (L5)) have been synthetised and characterised. Treatment of these compounds with AgSbF 6 generates dicationic complexes [(eta6-arene)Ru(pyam) (H2O)]2+ which act as enantioselective catalysts for the Diels-Alder reactions of methacrolein and cyclopentadiene. The catalytic reactions occur quickly at room temperature with good exo: endo selectivity (from 84: 16 to 98: 2) and moderate enantioselectivity (up to 74% ee). The molecular structures of the chloride complexes (RRu,S N,RC)-[(eta6-p-MeC6H 4iPr)RuClL1][SbF6], (RRu,S N,SC2)-[(eta6-p-MeC6H 4iPr)RuClL5][SbF6], and that of the aqua complex (RRu,SN,SC2)-[(eta6-p- MeC6H4iPr)RuL5(H2O)][SbF 6]2, were determined by X-ray diffractometric methods. The distinctive variations observed in the molecular structures of these complexes only concern the puckering parameters of the metallacycle and the relative disposition of substituents within this ring. A clear trend to localise the most steric demanding substituents at equatorial positions is evident from the structural study. The Royal Society of Chemistry 2008.

The reaction of the lithium salt of chlorodiphenylphosphine with 1-chloro-1-phenylsila-cyclopent-3-ene (1) and 1,1-dichlorosilacyclopent-3-ene (2) gave good yields of 1-((diphenylphosphino)methyl)-1-phenyl-1-silacyclopent-3-ene (L) (3) and 1,1-bis((diphenylphosphino)-methyl)-1-silacyclopent-3-ene (L?) (4). Both molecules were obtained as white solids characterized by NMR. Red and red-violet diamagnetic square-planar complexes trans-NiCl2L2 and cis-NiC2L? were obtained by reacting NiCl2¡¤6H2O with 3 and 4, respectively. Substitution of two PPh3 in CpRuCl(PPh3)2 by 4 gave CpRuCl(L?) (7) in good yield.

Facile synthesis of heterobimetallic [FeII(mu-diphosphine)RuII] and homobimetallic [FeII(mu-diphosphine)FeII] complexes and their in vitro cytotoxic activity on cisplatin-resistant cancer cells

A series of heterobimetallic [Fe,Ru] and homobimetallic [Fe,Fe] complexes, featuring mu -diphosphine bridges between the two metal centres, are reported along with their in vitro cytotoxicity activity on the A2780cisR cell-line. The known starting material [CpFe(CO)2(CH3)] (Cp = eta5-C5H5) (1) was reacted with dppe (1,2-bis(diphenylphosphino)ethane) forming the known mononuclear kappa1-dppe complex: [CpFe(CO)(COCH3)(kappa1-dppe)] (2) and the known dinuclear complex: and [[CpFe(CO)(COCH3)]2(mu-dppe)] (3). Dimer cleavage reactions between complex 2 and two ruthenium arene complexes [(eta6-p-cymene)RuCl2]2 and [(eta6-benzene)RuCl2]2 formed two new heterobimetallic complexes: [CpFe(CO)(COCH3)(mu-dppe)Ru(eta6-cymene)Cl2] (4) and [CpFe(CO)(COCH3)(mu-dppe)Ru(eta6-C6H6)Cl2] (5). A homobimetallic system, [[CpFe(CO)(I)]2(mu-dppb)] (6) was obtained by the facile reaction between of [CpFe(CO)2I] and 1,4-bis(diphenylphosphino)butane (dppb). Complex 6 was methylated using MeLi to generate the more lipophilic complex [[CpFe(CO)(CH3)]2(mu-dppb)] (7). All of the complexes were fully characterized by spectroscopy (1H, 13C {1H}, 31P {1H} NMR; FTIR, UV?Vis), and high resolution mass spectrometry (HRMS). Density functional theory calculations (DFT) (Level of theory B3LYP, basis set for H, C, P, O, Cl is 6-31+G(d,p) and for Ru, Fe, I is DGDZVP) on complexes 5 and 6 are also reported. An excellent agreement between the DFT calculated infra-red (IR) spectra of the optimised geometries of 5 and 6 was found with the experimentally determined spectra. In vitro cytotoxicity studies of all complexes was carried out on A2780cisR (cisplatin resistant ovarian cancer cell-line) and compared to cisplatin as a positive control and RAPTA-C as a negative control. Although limited to only one cell-line, the results show that the heterobimetallic complexes 4 and 5 are the most cytotoxic (IC50 = 4.9 ¡À 0.4 muM and 6.5 ¡À 0.1 muM respectively), whilst the dinculear [Fe,Fe] complexes exhibit no, or very low cytotoxicity.

Half sandwich complexes of chalcogenated pyridine based bi-(N, S/Se) and terdentate (N, S/Se, N) ligands with (eta6-benzene)ruthenium(ii): Synthesis, structure and catalysis of transfer hydrogenation of ketones and oxidation of alcohols

The half sandwich complexes [(eta6-C6H 6)Ru(L)Cl][PF6] (1-5) have been synthesized by the reactions of (2-arylchalcogenomethyl)pyridine [L = L1-L3] and bis(2-pyridylmethyl)chalcogenide [L = L4-L5] (chalcogen = S, Se; Ar = Ph/2-pyridyl for S, Ph for Se) with [(eta6-C6H 6)RuCl2]2, at room temperature followed by treatment with NH4PF6. Their HR-MS, 1H, 13C{1H} and 77Se{1H} NMR spectra have been found characteristic. The single crystal structures of 1-5 have been established by X-ray crystallography. The Ru has pseudo-octahedral half sandwich “piano-stool” geometry. The complexes 1-5 have been found efficient for catalytic oxidation of alcohols with N-methylmorpholine-N-oxide (NMO) and transfer hydrogenation of ketones with 2-propanol (at moderate temperature 80 C) as TON values are up to 9.9 ¡Á 103 and 9.8 ¡Á 103 respectively for the two catalytic reactions. On comparing the required catalyst loading for good conversions and reaction time for the present complexes with those reported in literature for other transfer hydrogenation/oxidation catalysts, it becomes apparent that 1-5 have good promise. The complexes of Se ligands have been found more efficient than their sulphur analogues. The complexes of bidentate ligands are more efficient than those of terdentate, due to difficult bond cleavage in the case of latter. These orders of efficiency are supported by DFT calculations. The calculated bond lengths/angles by DFT are generally consistent with the experimental ones.
