The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,4-Dibromobutane( cas:110-52-1 ) is researched.COA of Formula: C4H8Br2.Yang, Lu; Nie, Cui-Yun; Han, Ying; Sun, Jing; Yan, Chao-Guo published the article 《Self-assembly of bis-[1]rotaxanes based on diverse thiourea-bridged mono-functionalized dipillar[5]arenes》 about this compound( cas:110-52-1 ) in Journal of Inclusion Phenomena and Macrocyclic Chemistry. Keywords: bisrotaxane thiourea dipillararene self assembly NOESY spectra. Let’s learn more about this compound (cas:110-52-1).
Abstract: The condensation reaction of mono-amido-functionalized pillar[5]arenes with tere- and iso-phthaloyl diisothiocyanates in acetone under ultrasonic irradiation afforded tere- and iso-phthaloylthiourea-bridged dipillar[5]arenes. The similar reaction of mono-amido-functionalized pillar[5]arenes with 1,ω-bis(4-isothiocyanatophenoxy)alkanes also afforded diphenoxyalkylene thiourea-bridged dipillar[5]arenes. 1H NMR and NOESY spectra clearly indicated that bis-[1]rotaxanes were formed by insertion of longer alkylene chains into the cavities of two pillar[5]arenes. On the other hand, the free-forms of dipillar[5]arenes were obtained with the shorter ethylene chains existing on the outside of the cavities of two pillar[5]arenes.
