Photochemical Epoxidation of Olefins with Molecular Oxygen Activated by Oxo(tetra-p-tolylporphinato)molybdenum(V)

Photochemical epoxidation of olefins was catalyzed by a molybdenum porphyrin in benzene under aerobic conditions.The catalytic reaction rate was somewhat lower than that observed for the similar reactions catalyzed by the corresponding niobium complex.A reaction mechanism, involving cooperative interaction of an olefin and dioxygen with the molybdenum(V) species, was postulated.

Kinetics of the Reaction between Ethylperoxy Radicals and Nitric Oxide

The kinetic of the C2H5O2 + NO -> C2O5O + NO2 reaction is examined by two real-time techniques.NO consumption and NO2 formation are measured using transient diode laser absorption, whereas ethylperoxy loss and ethylnitrite formation are monitored by time-resolved UV spectrometry.Simultaneous fits of the NO and NO2 concentration versus time profiles yield rate constants consistent with the results of the C2H5O2 and C2H5ONO measurements.The combined data yield a rate constant of k5 = (3.1-1.0+1.5)E-12 e (330+/-11)/T cm3 s-1 over the 220-355 K temperature range.The small negative temperature dependence is consistent with the accepted mechanism of the reaction proceeding through a C2H5O2NO adduct.

Generation, Thermodynamics, and Chemistry of the Diphenylcarbene Anion Radical (Ph2C.-)

Dissociative electron attachment with Ph2C=N produced Ph2C.- (m/z 166).The reactions of Ph2C.- with potential proton donors of known gas-phase acidity were used to bracket PA(Ph2C.-) = 380 +/- 2 kcal mol-1 from which ΔHf0(Ph2C.-) = 81.8 +/- 2 kcal mol-1 was calculated.The reactions of Ph2C.- with CH3OH and C2H5OH proceeded with major and minor amounts, respectively, of a H2.+-transfer channel, forming Ph2CH2, RCHO, and an electron.The kinetic nucleophilicity of Ph2C.- in SN2 displacement reactions with CH3X and C2H5X molecules was shown to be medium, which requires a significant intrinsic barrier in these reaction.The reactions of Ph2C.- with various aldehydes, ketones, and esters were fast and established two principal product-forming channels: (1) H+ transfer if the neutral reactant contains activated C-H bonds and (2) carbonyl addition followed by radical β-fragmentation of one of the groups originally attached to the carbonyl carbon.The order for the ease of radical β-fragmentation in the tetrahedral intermediates was RO > alkyl >> H, and CO2CH3 > CH3.Since the reactions of Ph2C.- with the simple esters HCO2CH3 and CH3CO2CH3 were fast, it should now be possible to examine the reactions of carbonyl-containing organic molecules, which are expected to react slower than these esters and obtain their relative reactivities.
