So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Dudina, N. A.; Berezin, M. B.; Guseva, G. B.; Semeikin, A. S. researched the compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate( cas:2199-44-2 ).COA of Formula: C9H13NO2.They published the article 《Synthesis and spectral properties of 3,3′-bis(dipyrrolylmethene)》 about this compound( cas:2199-44-2 ) in Russian Journal of General Chemistry. Keywords: pyrrole carboxylate benzaldehyde pyrrolylaldehyde condensation; dipyrrolylmethene preparation; pyrrolylidene pyrrolemethane preparation. We’ll tell you more about this compound (cas:2199-44-2).
Bis(2,4,7,8,9-pentamethyldipyrrolylmethen-3-yl)(4′-methoxyphenyl)methane dihydrobromide was synthesized and its spectral properties were studied. The basicity of the ligand 3,3′-bis-(dipyrrolylmethene) decreases upon insertion of the methoxyphenyl group in the 3,3′-spacer.
Compounds in my other articles are similar to this one(Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate)COA of Formula: C9H13NO2, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
