Recommanded Product: 2199-44-2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate, is researched, Molecular C9H13NO2, CAS is 2199-44-2, about Nuclear magnetic resonance study of carbethoxypyrroles. Author is Roomi, Mohammad W.; Dugas, H..
The chem. shifts and the ring proton coupling constants of various substituted carbethoxypyrroles are reported. The electron-withdrawing effect of the carbethoxy groups shifts the resonances of the ring substituents to low field while the inductive and mesomeric effects of the Me groups shift the resonances to higher field. The deshielding effect is more pronounced with 2-carbethoxypyrroles than for 3-carbethoxypyrroles. The ring proton spin-spin coupling constants depend on the nature of substituents and increase with the electronegativity of the substituents. In some cases, long-range coupling between the Me side-chain protons and ring protons was observed.
After consulting a lot of data, we found that this compound(2199-44-2)Recommanded Product: 2199-44-2 can be used in many types of reactions. And in most cases, this compound has more advantages.
