Catalan, Javier; Perez, Pilar; Elguero, Jose published the artcile< Substituent effects on proton affinities: through bonds or through space mechanism?>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is MO pyrazole imidazole; protonation energy pyrazole imidazole; lone pair orbital energy heterocycle.
INDO calculations of the protonation energies and lone pair orbital energies of twenty pyrazoles and twenty imidazoles have been carried out in order to ascertain the mechanism of the substituent effect; Me, cyano, fluoro, amino, and nitro substituents have been examined The nitro group shows a special behavior. The importance of optimizing the geometry and the reasons for the anomaly shown by the nitro derivatives are discussed.
Heterocycles published new progress about Electronic state. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
