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.Mevissen, Christian; Kwamen, A. Carel N.; Himmel, Leonard; Chen, Xiaofei; Brueckner, Matthias; Huda, Saskia; Goeb, Christian; Jenniches, Judith; Oppel, Iris; Ward, Jas S.; Rissanen, Kari; Albrecht, Markus researched the compound: 2-(2-Bromoethoxy)tetrahydro-2H-pyran( cas:17739-45-6 ).Application of 17739-45-6.They published the article 《Helicates with Ether-Substituted Catechol Esters as Ligands》 about this compound( cas:17739-45-6 ) in European Journal of Organic Chemistry. Keywords: titanium lithium catechol complex preparation; crystal structure titanium lithium catechol complex. We’ll tell you more about this compound (cas:17739-45-6).
Mono- or biscatechol esters with ether-type substituents or spacers form either triple lithium bridged dimeric helicates or triple stranded helicates with the ability to bind three lithium cations in their interior. Hierarchical helicates with ether or thioether substituents show in solution a monomer-dimer equilibrium which is independent of the heteroatom in the ester substituent. However, dimerization constants are significantly lower than for corresponding alkyl derivatives Dinuclear helicates with oligoether spacers are well obtained in the presence of lithium cations. Upon removal of the cations the helicates expand and successive addition of LiCl results in compression again.
The article 《Helicates with Ether-Substituted Catechol Esters as Ligands》 also mentions many details about this compound(17739-45-6)Application of 17739-45-6, you can pay attention to it, because details determine success or failure
