New polyoxygenated cyclohexene and polyoxygenated seco-cyclohexene from Uvaria boniana

Journal of Asian Natural Products Research, 2013
A new polyoxygenated cyclohexene bonianol A (1) and another new polyoxygenated seco-cyclohexene bonianol B (2) were isolated from the leaves of Uvaria boniana, and their structures were established on the basis of spectroscopic methods including IR, HR-ESI-MS, 1D, and 2D NMR.

Electron ionization of cyclohexene

Journal of Physics B: Atomic, Molecular and Optical Physics, 2014
The absolute total cross section of electron ionization on cyclohexene (CHE) and the branching ratios of the product ions are measured in an electron energy range of 10–200 eV. The total cross section reaches a maximum of 1.5 × 10−15 cm2 at 80 eV. Sixteen noteworthy product ions are observed from the ionization of CHE that have partial cross sections ...

On the ring interconversion of cyclohexene

Journal of Molecular Structure, 1972
Abstract Possible interconversion paths of the cyclohexene molecule are considered, from the point of view of a molecular mechanical model. The application of the modified valley method to the search of the potential function's saddle points arrived at the boat transition state, the calculated barrier being in agreement with NMR experiment.

Ultrafast Dynamics of Cyclohexene and Cyclohexene-d₁₀ Excited at 200 nm

Journal of the American Chemical Society, 2001
By exciting cyclohexene in the gas phase at 200 nm and probing it by nonresonant multiphoton ionization with mass-selective detection of the ion yields, we found four time constants tau(i) (20, 47, 43, 350 fs). Whereas deuteration lengthens tau2 by a factor of 1.4, the other constants do not change.

Kinetics and mechanism of the hydrogenation of cyclohexene

International Journal of Chemical Kinetics, 1975
AbstractThe rate of hydrogenation of cyclohexene, catalyzed by CoH3(PPh3)3, has been measured under various conditions and, based on these data, a mechanism has been postulated. For the individual steps of the mechanism enthalpy and entropy differences have been determined.

Interaction of mercaptans with cyclohexene

Petroleum Chemistry U.S.S.R., 1980
A study was made of thermal interaction of ethanethiol, n-propane-1-thiol, isopropanol, n-butane-1-thiol and n-pentanethiol with cyclohexene in a wide range of temperature, space velocity and molar ratios of reagents in the continuous system. The corresponding alkylcyclohexylsulfides are the main reaction products.

Enantioselective synthesis of cyclohexene nitroaldehydes

Tetrahedron Letters, 1989
AbstractThe acetoxylated manno‐ (Ia) or galacto‐nitroalkenes (Ib) are subjected to Diels‐Alder reaction with 2,3‐dimethylbutadiene (II) to form the cyclohexenes (III) and (IV).

THE RADIOLYSIS OF CYCLOHEXANE: II. CYCLOHEXANE–CYCLOHEXENE SOLUTIONS AND PURE CYCLOHEXENE

Canadian Journal of Chemistry, 1960
The γ-radiolysis of cyclohexane–cyclohexene solutions and of pure cyclohexene has been investigated. The previously determined yields of the two activated species in irradiated cyclohexane have been confirmed. G(c-C6H12′′) = 3.0 ± 0.3 and G(c-C6H12′) = 2.4 ± 0.3.The yields of the main products of cyclohexene radiolysis are G(H2) = 1.2, G(c-C6H12) = 1 ...
