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.Zhang, Y.; Wang, Z.; Yan, C.; Li, G.; Ma, J. researched the compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate( cas:2199-44-2 ).Quality Control of Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate.They published the article 《Synthesis and self-assembly of a novel tetrapyrrole containing dipyrrin units linked at the 3,3′-positions》 about this compound( cas:2199-44-2 ) in Tetrahedron Letters. Keywords: dipyrrin tetrapyrrole preparation selfassembly; zinc tetrapyrrole complex preparation crystal structure; mol structure zinc tetrapyrrole complex. We’ll tell you more about this compound (cas:2199-44-2).
A novel ligand comprising two dipyrrin units linked by a CH2 spacer at the 3-position was synthesized and used to prepare a double-stranded helical assembly. Its structure was confirmed by x-ray anal. of its Zn complex. A new approach to 3,3′-linked dipyrromethanes with CH2 as the spacer is also reported.
When you point to this article, it is believed that you are also very interested in this compound(2199-44-2)Quality Control of Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate and due to space limitations, I can only present the most important information.
