The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-(Bromomethyl)-4-iodobenzene( cas:16004-15-2 ) is researched.Application In Synthesis of 1-(Bromomethyl)-4-iodobenzene.Broloes, Line; Klaue, Kristin; Bendix, Jesper; Grubert, Lutz; Hecht, Stefan; Nielsen, Mogens Broendsted published the article 《Stabilizing Indigo Z-Isomer through Intramolecular Associations of Redox-Active Appendages》 about this compound( cas:16004-15-2 ) in European Journal of Organic Chemistry. Keywords: cross coupling fused ring photochromism sulfur heterocycle supramol isomerization. Let’s learn more about this compound (cas:16004-15-2).
Photoswitchable small mols., such as N,N’-disubstituted indigos, have received great interest within fields such as pharmacol., energy storage, and functional materials, as they represent key building blocks for reversible and non-invasive control of chem. processes. However, to ensure applicability of photochromic systems it is of paramount importance to manipulate the photostationary state. In this work, we achieved this by tethering two redox-active indenofluorene-extended tetrathiafulvalene units to an N,N’-disubstituted indigo photoswitch. Upon two-electron oxidation, we observe significantly enhanced stability of the Z-isomer, compared to the neutral compound, illustrated by a substantial increase in the half-life from 0.48 s to 22 h. This remarkable stabilization is ascribed to formation of strong, intramol. π-dimers between the oxidized subunits.
