Hydrocarbon Oxidation with H2O2, Catalyzed by Iron Complexes with a Polydentate Pyridine-Based Ligand
We report the structural and functional features of two new catalysts: a mononuclear [Fe(N5mpy)(CH3CN)] (BF4)2 (N5mpy = (N,N 0E,N,N0E)-N,N0-(pyridine-2,6-diylbis (ethan-1-yl-1-ylidene))bis(1-(pyridin-2-yl)methanamine)) complex and a binuclear {[Fe(N5mpy)]2O}(BF4)4 complex. Both compounds catalyze the oxidation of alkanes by H2O2, in MeCN or acetone to yield alcohols and ketones. Moderate to goo...
متن کاملAu nanoparticles in carbon nanotubes with high photocatalytic activity for hydrocarbon selective oxidation.
High-efficiency and high-selectivity catalytic oxidation of alkanes under mild conditions with air is a major aim of current catalytic chemistry and chemical production. Despite extensive development efforts on new catalysts for cyclohexane oxidation, current commercial processes still suffer from low conversion, poor selectivity, and excessive production of waste. Here, we present the design a...
متن کاملInfrared spectroscopy of discrete uranyl anion complexes.
The Free-Electron Laser for Infrared Experiments (FELIX) was used to study the wavelength-resolved multiple photon photodissociation of discrete, gas-phase uranyl (UO22+) complexes containing a single anionic ligand (A), with or without ligated solvent molecules (S). The uranyl antisymmetric and symmetric stretching frequencies were measured for complexes with general formula [UO2A(S)n]+, where...
متن کاملMacrolactonization via hydrocarbon oxidation.
A novel Pd/sulfoxide-catalyzed macrolactonization reaction of linear omega-alkenoic acids is reported that proceeds via serial ligand-catalyzed allylic C-H oxidation. The scope of this macrolactonization appears to be very broad. Aryl, alkyl, and (Z)-alpha,beta-unsaturated acids are all competent nucleophiles for this reaction, with the latter undergoing macrolactonization with no olefin isomer...
متن کاملEasy access to stable pentavalent uranyl complexes.
Reaction of UO2I2(THF)3 with 1 molar equivalent of KC5R5 (R = H, Me) in pyridine led to the uranyl(V) compound {[UO2(Py)5][KI2(Py)2]}(infinity), which is an infinite 1D polymer in its crystalline form; the UO2X(THF)n (X = I, OSO2CF3) complexes were obtained by reduction of their U(VI) parents with TlC5H5 or KC5R5 in THF.
