In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis and spectral properties of new 3,3′-bis(dipyrrolylmethene) with acetylene spacer, published in 2010-11-30, which mentions a compound: 2199-44-2, mainly applied to bistetramethyl ethyldipyrrolylmethenyl acetylene dihydrobromide preparation; quantum chem simulation conformation spectral, Recommanded Product: 2199-44-2.
Bis(2,4,7,9-tetramethyl-8-ethyldipyrrolylmethen-3-yl)acetylene dihydrobromide (H2L·2HBr), new bis(dipyrrolylmethene), in whose mol. dipyrrolylmethene domains were connected through 3,3′-carbon atoms of internal pyrrole nuclei by acetylene spacer, were synthesized by original procedure. The compound was characterized by element anal., IR, 1H NMR, and electronic spectroscopy. The comparative anal. of spectral properties shows the reduction of the basicity of H2L ligand in comparison with the structural analogs, which contain internal methylene spacer. The quantum-chem. simulation showed that the rigid acetylene spacer gives linear structure to the H2L mol. in contrast to the spiral-shaped geometry of structural analogs with -CH2- spacer.
There is still a lot of research devoted to this compound(SMILES：O=C(C1=C(C)C=C(C)N1)OCC)Recommanded Product: 2199-44-2, and with the development of science, more effects of this compound(2199-44-2) can be discovered.
