Asymmetric Allylation/RCM-Mediated Synthesis of Fluorinated Benzo-Fused Bicyclic Homoallylic Amines As Dihydronaphthalene Derivatives

Enantiomerically enriched fluorinated benzo-fused bicyclic homoallylic amines have been synthesized through an asymmetric allylation/ring closing metathesis (RCM) sequence. This sequence has been carried out using alpha-trifluoromethylstyrene derivatives as key intermediates, synthesized by microwave radiation. The great deactivating effect exerted by such substituents has been brought to light by a comparative study.

Insights into hydrogen generation from formic acid using ruthenium complexes

The decomposition of a HCO2H/Et3N azeotrope to a mixture of hydrogen and carbon dioxide may be catalyzed by a number of Ru(III) and Ru(II) complexes with high efficiency at ca. 120 C. Evidence that suggests that the precatalyst may in each case be a common ruthenium dimer has been obtained through 1H NMR and X-ray crystallographic studies of the complexes formed in situ and of analysis of the gases generated in the reaction using FTIR and gas chromatography methods.

Synthesis of the water soluble ligands dmPTA and dmoPTA and the complex [RuClCp(HdmoPTA)(PPh3)](OSO2CF3) (dmPTA = N,N?-dimethyl-1,3,5-triaza-7-phosphaadamantane, dmoPTA = 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane, HdmoPTA = 3,7-H-3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane)

The new water-soluble ligand dmPTA(OSO2CF3) 2 (1) (dmPTA = N,N?-dimethyl-1,3,5-triaza-7-phosphaadamantane) has been synthesized by reaction of PTA with MeOSO2CF3 in acetone (PTA = 1,3,5-triaza-7-phosphatricycle[3.3.1.13,7]decane). The reaction of 1 with KOH gave rise to the new water-soluble ligand dmoPTA (3) (dmoPTA = 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) by elimination of the -CH2- group located between both NCH3 units. Compound dmPTA(BF4)2 (2) and complex [RuClCp(HdmoPTA)(PPh3)](OSO2CF3) (4) have also been synthesized, while compounds HdmoPTA(BF4) (3a) and [RuClCp(dmPTA)(PPh3)](OSO2CF3) (5) were characterized but not isolated. The new ligands and the complex have been fully characterized by NMR, IR, elemental analysis, and X-ray crystal structure determination (ligand 1 and complex 4). The synthetic processes for 3 and 4 were studied.

Effect of electronic resistance and water content on the performance of RuO2 for Supercapacitors

Hydrous ruthenium oxide, Ru O2 H2 O, was prepared according to a sol-gel process and annealed at different temperatures. The importance of high electronic conductivity for high capacity in aqueous 3 M H2 S O4 was revealed through two approaches. The electronic resistivity of Ru O2 H2 O measured in situ as a function of the electrode potential shows a marked increase toward low potentials. This trend is more pronounced for the low-temperature annealed oxide (T?150C) where it results in a limitation of the capacitance at E<0.4 V vs reversible hydrogen electrode. This finding is in line with the steep rise of the electrochemical impedance in the same potential region. A possible way to overcome this limitation is to mix two differently heat treated oxides, one with high conductivity (T=300C, Z300), the other with optimum capacity (T=150C, Z150). The observed specific capacity increase of hydrous Ru O2 in the mixture from 738 to 982 Fg is attributed to an improvement of the electronic pathway along the particles of high-temperature-treated Ru O2 (Z300) toward the high-capacity Z150 particles. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

A metathesis-acylation approach to the bicyclic core of polycyclic poly-prenylated acylphloroglucinols

An approach to a model compound for polycyclic polyprenylated acylphloroglucinols is developed using a ring-closing metathesis approach to give a substituted cyclooctene. This undergoes cyclization via an intramolecular acylation leading to a substituted bicyclo[3.3.1]nonan-9-one related to hyperforin, nemorosone, clusianone, garsubellin A and other members of the polyprenylated acylphloroglucinol.

All these complexes are isolated as hexafluorophosphate salts and characterized by IR, NMR, mass spectrometry and UV-Vis spectroscopy. The molecular structures of [2]PF6and [9]PF6have been established by single-crystal X-ray structure analyses.

Dialkylamino cyclopentadienyl ruthenium(II) complex-catalyzed alpha-alkylation of arylacetonitriles with primary alcohols

Aminocyclopentadienyl ruthenium complexes, [(eta5-C 5H4NMe2)Ru(PPh3)2(CH 3CN)]+BF4- and [(eta5- C5H4NEt2)Ru(PPh3) 2(CH3CN)]+BF4-, are moderately active catalysts for alpha-alkylation of arylacetonitriles with primary alcohols; on the other hand, the analogous unsubstituted cyclopentadienyl ruthenium complex [(eta5-C5H 5)Ru(PPh3)2(CH3CN)] +BF4- shows very low catalytic activity. On the basis of experimental results and theoretical calculations, rationalization for the much higher catalytic activity of the aminocyclopentadienyl complexes over that of the unsubstituted Cp complex is provided. In the catalytic systems with the former, it is possible to regenerate the active solvento complexes via protonation of the metal hydride intermediates and subsequent ligand substitution; this process is, however, very nonfacile in the catalytic system with the latter.

16-electron (arene)ruthenium complexes with superbasic bis(imidazolin- 2imine) ligands and their use in catalytic transfer hydrogenation

The ligands N,N’-bis(l,3,4,5-tetramethylimidazolin-2-ylidene)-l,2- ethanediamine (BLMe) and N,N-bis(l,3-diisopropyl-4,5- dimethylimidazolin-2-ylidene)-l,2-ethanediamine (BLIPr) react with [(eta5-C5Me5)RuCl]4 to afford cationic 16electron half-sandwich complexes [(eta5-C 5Me5)Ru(BLR)]+ (R = Me, 3; R = iPr, 4), which resist coordination of the chloride counterion because of the strong electron-donating ability of the diimine ligands. Upon reaction with [(eta6-C6H6)RuCl2]2 or [(eta6-C10H14)RuCl2]2, these ligands stabilize dicationic 16electron benzene and cymene complexes of the type [(eta6C6H6)Ru(BLR)] 2+ (R = Me, 5; R = iPr, 6) and [(eta6-C 10H14)Ru(BLR)]2+ (R = Me, 7; R = iPr, 8). The X-ray crystal structure of [5]C12 reveals the absence of any direct Ru-Cl interaction, whereas a long Ru-Cl bond, supported by two CH-C1 hydrogen bonds, is observed for [(6)Cl]Cl in the solid state.
