Category: chiral-oxygen-ligands. 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: 3-Methyl-1H-pyrrole, is researched, Molecular C5H7N, CAS is 616-43-3, about Analysis of the NMR spectrum of 3-methylpyrrole. Author is Fukui, H.; Shimokawa, S.; Sohma, J.; Twadare, T.; Esumi, N..
Earlier work (F., S., S., 1970) on pyrrole and on its 2-derivatives is extended to 3-methylpyrrole. Observed and simulated spectra are shown for the N-decoupled spectra at 60 MHZ, and for the N-H proton in which the 14N nucleus and Me protous were decoupled and the 5-proton was perturbed. The chem. shills and coupling constants are tabulated. The best simulated spectrum is a 7-spin system. The compound was dissolved in acetone-d, with Me4Si as internal reference
As far as I know, this compound(616-43-3)Category: chiral-oxygen-ligands can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
