Synthesis and transition metal chemistry of ferrocenylbis(benzo-oxazaphosphininone)

The new ferrocenylbis(oxazaphosphininone), [Fe{C5H4P(OC6H4)(CO)N-(C2H4Cl)}2] (1) was synthesized by the reaction of bis(dichlorophosphino)ferrocene with two equivalents of 2(2?-hydroxy)phenyloxazoline in the presence of triethylamine in 83% yield. The reactions of 1 with aq. H2O2 or elemental sulfur afforded bis-chalcogenides [Fe{C5H4P(E)(OC6H4)(CO)N(C2H4Cl)}2] (2 E = O, 3 E = S). Treatment of 1 with [M(CO)4(C5H11N)2] (M = Mo, W), [RuCp(PPh3)2Cl] and [M(COD)Cl2] (M = Pd, Pt) afforded the chelate complexes [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{M(CO)4}] (4 M = Mo, 5 M = W), [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{RuCp(Cl)}] (7) and [Fe{C5H4P(OC6H4) (CO)N(C2H4Cl)}2{MCl2}] (8 M = Pd, 9 M = Pt), whereas the reaction of 1 with [Ru(eta6-p-cymene)Cl2]2, yielded a bimetallic complex [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{RuCl2(eta6-p-cymene)}2] (6). The reaction between 1 and CuX in equimolar ratio also yielded binuclear complexes, [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{CuX}2] (10 X = Cl, 11 X = Br, 12 X = I).

Rate acceleration in olefin metathesis through a fluorine-ruthenium interaction

The synthesis, structure, and performance of new ruthenium-based olefin metathesis catalysts, featuring fluorinated NHC ligands are presented. The introduction of halogen atoms into the N-heterocyclic carbene ligand profoundly alters the catalytic activity and can afford a more efficient catalyst. Structural investigations suggest that a fluorine-ruthenium interaction is responsible for this increased activity. Copyright

Studies on an (S)-2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA) receptor antagonist IKM-159: Asymmetric synthesis, neuroactivity, and structural characterization

IKM-159 was developed and identified as a member of a new class of heterotricyclic glutamate analogues that act as AMPA receptor-selective antagonists. However, it was not known which enantiomer of IKM-159 was responsible for its pharmacological activities. Here, we report in vivo and in vitro neuronal activities of both enantiomers of IKM-159 prepared by enantioselective asymmetric synthesis. By employment of (R)-2-amino-2-(4- methoxyphenyl)ethanol as a chiral auxiliary, (2R)-IKM-159 and the (2S)-counterpart were successfully synthesized in 0.70% and 1.5% yields, respectively, over a total of 18 steps. Both behavioral and electrophysiological assays showed that the biological activity observed for the racemic mixture was reproduced only with (2R)-IKM-159, whereas the (2S)-counterpart was inactive in both assays. Racemic IKM-159 was crystallized with the ligand-binding domain of GluA2, and the structure revealed a complex containing (2R)-IKM-159 at the glutamate binding site. (2R)-IKM-159 locks the GluA2 in an open form, consistent with a pharmacological action as competitive antagonist of AMPA receptors.

Synthesis of a ruthenium(II) complex containing an [11]ane-P 2CNHC (NHC = Imidazolidin-2-ylidene) macrocycle

Reaction of [RuCl(Cp)(PPh3)2] with bis[di(2-fluorophenyl)phosphino]benzene, 3, yields complex [RuCl(Cp)(3)], [4]. The chloro ligand in [4] can be exchanged for the 2-azidoethyl isocyanide ligand 2, giving complex [Ru(Cp)(2)(3)]Cl, [5]Cl, which reacts with NH 4BF4 to give [5]BF4. The azido group of the coordinated isocyanide ligand in [5]C1 or [5]BF4 can be reduced with Zn/NH4Cl/H2O to give the complex with the 2-aminoethyl isocyanide ligand. This ligand is not stable but cyclizes by an intramolecular nucleophilic attack of the amino group at the isocyanide carbon atomto give an NH, NH-stabilized NHC ligand in complexes [6]X (X = Cl, [6]C1; X = 0.5 ZnCl 4, [6]2(ZnCl4); X = BF4, [6]BF 4). Deprotonation of the NH,NH-stabilized NHC ligands in cations of type [6]+ leads to an intramolecular nucleophilic attack of the amido nitrogen atoms at the fluorinated phenyl groups of the diphosphine ligand under formation of the complex with the facially coordinated macrocyclic [11]ane-P2CNHC ligand [1]X (X = Cl, [1]Cl; X = 0.5 ZnCl4, [1]2(ZnCl4); X = BF4, [1]BF4). Formation of the macrocycle is facilitated by the steric pressure excerted by the cyclopentadienyl ligand. The molecular structures of [4], [5]BF4, [6]BF4-CH2Cl2, and [1]Cl¡¤CH2Cl2¡¤0.5H2O have been determined by X-ray diffraction.

Organometallic ionic liquids from half-sandwich Ru(II) complexes with various chelating ligands

Salts comprising of cationic half-sandwich Ru(II) complexes with various chelating ligands and the bis(trifluoromethanesulfonyl)amide anion (Tf2N-) were prepared. These salts can be represented as [(arene)RuCl(L-L)][Tf2N] (arene = C6Me5Bu, C6Me6, p-cymene, C6H6; L-L = 2-Py-CH2NHCMe2Et, 2-Py-CH=NC6H13, H13C6NHCH2CH2NHC6H13, Me2NCH2CH2SC4H9, Me2CN=CHCH=NCMe2). Two of the eight salts are liquids at room temperature (?20 C), while the other salts are solids with melting points of 60-130 C. Upon cooling from the melt, most salts exhibited glass transitions between -30 C and -5 C. The salts were found to catalyze the oxidation of cyclohexanol although decomposition occurred during the reaction. Crystal structures of related salts were also determined.
