Recommanded Product: 2199-44-2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate, is researched, Molecular C9H13NO2, CAS is 2199-44-2, about Free energy relationships of ionization energies measured by ultraviolet photoelectron spectroscopy in substituted pyrroles. Author is Cauletti, Carla; Giancaspro, Carlo; Monaci, Anna; Piancastelli, M. Novella.
The ionization energies of six 5-substituted-3-ethoxycarbonyl-2,4-dimethylpyrroles and seven 4-substituted 2-ethoxycarbonyl-3,5-dimethylpyrroles were determined by UPS. The relations between the lowest ionization potentials and σ were determined and the different influence of substituents in the α- and β-positions is discussed.
