Synthesis, structure, and catalytic property of a mononuclear dioxomolybdenum(VI) complex containing MoON core

Reaction of molybdenyl(IV) oxide bis(2,4-pentanedionate) with N'-(3-ethoxy-2-hydroxybenzylidene)-2-methoxybenzohydrazide in methanol affords a mononuclear dioxomolybdenum(VI) complex containing MoO5N basic core. The complex has been characterized by various physicochemical techniques (IR and elemental analysis), and single crystal X-ray diffraction. X-ray crystal structure determination reveals that the complex crystallizes as monoclinic space group P21/c, with unit cell dimensions a = 9.251(1), b = 11.910(2), c = 17.636(3) A, β = 103.220(2)°, V = 1891.7(5) A3, Z = 4, R 1 = 0.0693, wR 2 = 0.1691. The Mo atom in the complex is octahedrally coordinated, with the tridentate ONO ligand occupying the meridional sites. Thermal stability analysis was performed. The complex shows high catalytic property for the oxidation of various olefins.

FTIR Spectroscopic Study of the Cl-Atom-Initiated Reactions of Ethylene Oxide in O2/N2 Diluent

A long-path FTIR spectroscopic study of the Cl-atom-initiated reactions of ethylene oxide was carried out at 297+/-2 K in the photolysis (300 mn) of mixtures containing and Cl2 in both the torr millitorr ranges in 700 Torr of N2 or O2/N2 diluent.In 700 Torr of N2, the only primary product detected was , formed via (1) Cl+ -> + HCl followed by (2) + Cl2 -> + Cl.Thus, the cyclic oxiranyl radical formed in reaction 1 was sufficiently long-lived to react with Cl2.An upper limit value of k34 s-1 has been esmimated for the rate constant of the possible oxiranyl-to-vinoxy isomerization: (3) -> CH2CHO.The yield decreased with increase in added O2 due to the occurrence of reaction 4: (4) + O2 (+M) -> (+M).A value of k2/k4=2.0+/-0.4 was derived from the O2 dependence of the yield.In 700 Torr of air, the observed products included C-O-C bonded compounds HC(O)OCHO and CH2(OH)OCHO, and one-carbon species CO, CO2, HCHO, and HC(O)OH, but not C-C bonded products.The preferential formation of C-O-C rather than C-C bonded products suggests the predominant cleavage of the C-C bond rather than the C-O bond in a three membered ring precursor radical.The most likely candidate is the cyclic radical formed via self-reaction, i.e. -> + O2.A detailed mechanism is proposed for the oxidation of the radical leading to the formation of the observed products.

An Experimental Study of the Reactions CH3CHO + Cl, C2H4O + Cl, and C2H4O + F in the Gas-Phase

The reactions of chlorine and fluorine atoms with the structural isomers CH3CHO and C2H4O have been studied at low pressures and room temperature by the discharge flow technique with mass spectrometric detection.Using the reference reactions C2H6 + Cl --> C2H5 + HCl (0) C2H6 + F --> C2H5 + HF (00) the relative rate constant for the reactions CH3CHO + Cl --> products (1) C2H4O + Cl --> products (2) C2H4O + F --> products (3) were determined: k1/k0 = 1.04 +/- 0.09, k2/k0 = 0.49 +/- 0.04, k3/k00 = 0.47 +/- 0.05. - Reaction (1) proceeds mainly via hydrogen abstraction from the aldehyde group (>93percent) forming CH3CO.In the reactions of ethylene oxide (2), (3) the abstraction route is observed, contributions from addition channels in reaction (2) are discussed. - Keywords: Chemical Kinetics / Elementary Reactions / Mass Spectrometry / Radicals

Methoxychlorocarbene. Matrix Spectroscopy and Photochemistry

Irradiation of 3-chloro-3-methoxydiazirine matrix isolated in argon or nitrogen at 10 K gives methoxychlorocarbene.The carbene was observed by IR and UV spectroscopy.Deuterium and 18O labeling indicated significant C-O double bond character in the carbene, which was exhibited in an intense IR absorption at ca. 1300 cm-1.The time evolution and wavelength dependence of the IR bands indicate two geometric isomers for the carbene, with distinct IR absorptions.The cis-carbene shows a significantly lower energy C-Cl stretch than the trans, consistent with an anomeric interaction.Irradiation of the carbene gives acetyl chloride, ketene, and HCl in argon matrices.In nitrogen, small amounts of CO and methylchloride are also observed.Several mechanisms are proposed to explain the photochemical results.
