In 2022,Luz, Eduardo Q.; Santana, Francielli S.; Silverio, Gabriel L.; Tullio, Suelen C. M. C.; Iodice, Bianca; Prola, Lizie D. T.; Barbosa, Ronilson V.; Rampon, Daniel S. published an article in Acta Crystallographica, Section E: Crystallographic Communications. The title of the article was 《Crystal structures of 3-halo-2-organochalcogenylbenzo[b]chalcogenophenes》.Recommanded Product: 1,2-Diphenyldisulfane The author mentioned the following in the article:
The structure of the title compounds 3-bromo-2-(phenylsulfanyl)benzo[b]thiophene (C14H9BrS2; 1), 3-iodo-2-(phenylsulfanyl)benzo[b]thiophene (C14H9IS2; 2), 3-bromo-2-(phenylselanyl)benzo[b]selenophene (C14H9BrSe2; 3), and 3-iodo-2-(phenylselanyl)benzo[b]selenophene (C14H9ISe2; 4) were determined by single-crystal X-ray diffraction; all structures presented monoclinic (P21/c) symmetry. The Ph group is distant from the halogen atom to minimize the steric hindrance repulsion for all structures. Moreover, the structures of 3 and 4 show an almost linear alignment of halogen-selenium-carbon atoms arising from the intramol. orbital interaction between a lone pair of electrons on the halogen atom and the antibonding σ*Se-C orbital (nhalogen→σ*Se-C). This interaction leads to significant differences in the three-dimensional packing of the mols., which are assembled through π-π and C-H···π interactions. These data provide a better comprehension of the intermol. packing in benzo[b]chalcogenophenes, which is relevant for optoelectronic applications. The experimental process involved the reaction of 1,2-Diphenyldisulfane(cas: 882-33-7Recommanded Product: 1,2-Diphenyldisulfane)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Although ethers resist hydrolysis, they are cleaved by hydrobromic acid and hydroiodic acid. Hydrogen chloride cleaves ethers only slowly. Recommanded Product: 1,2-Diphenyldisulfane
