On the photoreaction of some 1,2,4-oxadiazoles in the presence of2,3-dimethyl-2-butene. Synthesis of N-imidoyl-aziridines
2007
Fhe photochemistry of some 3,5-disubstituted 1,2,4-oxadiazoles in the presence of 2,3-dimethyl-2-butene has been investigated. The irradiation in acetonitrile yielded differently substituted N-imidoyl-aziridines through an aziridination reaction involving an acyliminonitrene intermediate. Pyrolysis of N-imidoyl-aziridines produced the corresponding N-allylamidines through a ring opening process.

Switch in Relative Stability between cis and trans 2-Butene on Pt(111) as a Function of Experimental Conditions: A Density Functional Theory Study
2018
International audience; The adsorption of cis and trans 2-butenes on Pt(111) has been studied as a function of hydrogen coverage OH by means of calculations based on density functional theory (DFT) with the inclusion of dispersion forces. All hydrogen coverages have been considered, from 0 to 1.00 monolayer (ML). For each case, the di-sigma and pi adsorption geometries of the olefins have been compared at a surface coverage of theta(C4H8) = 0.11 ML. Calculations of the Gibbs free energies of these systems have identified the most stable 2-butene isomer (cis or trans) as a function of coverage, temperature, and pressure. In particular, focus was placed on two sets of conditions, namely, one …

A general mechanism for the reactions of the NO3 radical with 2-butene, isobutene, 2-methyl-2-butene, and 2,3-dimethyl-2-butene is proposed on the basis of density functional theory (DFT) calculati...
