Recommanded Product: 1,2-DiiodoethaneIn 2019 ,《Stable Cross-Conjugated Tetrathiophene Diradical》 was published in Angewandte Chemie, International Edition.

A tetracyano quinoidal tetrathiophene, having a central bi(thieno[3,4-c]pyrrole-4,6-dione) acceptor, has been studied. The recovered aromaticity of the thiophenes produces a diradical species with cross-conjugation between the inter-dicyano and inter-dione acceptor paths. A diradical character of y0=0.61 and a singlet-triplet gap of -2.76 kcal mol-1 were determined Competition between the two cross-conjugated paths enhances the disjointed character of the SOMOs and results in the confinement of the diradical to the mol. center, enabling a thermodn. diradical stabilization featuring a half-life of 262 h. Cross-conjugation effects have been also addressed in the anionic species (up to a radical trianion). In the experiment, the researchers used many compounds, for example, 1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 1,2-Diiodoethane)
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Recommanded Product: 1,2-Diiodoethane
