Application In Synthesis of Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate, is researched, Molecular C9H13NO2, CAS is 2199-44-2, about Carbon-13 nuclear magnetic resonance spectra of substituted pyrroles. Author is Abraham, Raymond J.; Lapper, Roy D.; Smith, Kevin M.; Unsworth, John F..
The 13C NMR spectra of 55 pyrroles were determined and assigned. The pyrrole ring carbon chem. shifts were predicted, to ∼0.5 ppm, on the basis of additive substituent effects and contributions from steric and conjugative effects. The substituent chem. shift parameters were analogous to those for thiophenes. C-2 substituents affected mainly C-3 and C-5, and C-3 substituents mainly C-2.
