3-Iodobenzo[b]thiophene (cas: 36748-88-6) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Related Products of 36748-88-6

Photochemistry of heterocyclic compounds. VII. Photochemical reaction of 2,5-diphenyl-1,3,4-oxadiazole with benzo[b]thiophenes was written by Oe, Koji;Tashiro, Masashi;Tsuge, Otohiko. And the article was included in Bulletin of the Chemical Society of Japan in 1977.Related Products of 36748-88-6 This article mentions the following:

Irradiation of 2,5-diphenyloxadiazole (I) with benzothiophene II (R = H) gives 3-benzoylbenzothiophene III (R1 = PhCO), its benzoylhydrazone [III; R1 = PhC(:NNHCOPh)], and/or the oxadiazepine IV; the yields depend on the nature of solvents. With Ph2CO as a sensitizer, the photochem. reaction of I with II (R = H) forms the [2+2] cycloadduct V. IV is photochem. dissociated to I and II (R = H). In the case of 2-methylbenzothiophene VI, 3-benzoyl-2-methylbenzothiophene benzoylhydrazone is formed, and with Ph2CO as a sensitizer the [2+2] cycloadduct II (R = Me) is obtained. In the absence or presence of Ph2CO, however, irradiation of I with 3-methylbenzothiophene gives the [2+2] cycloadduct VII. The photochem. reaction of I with II (R = H, Me) in the presence of iodine gives the corresponding 3-benzoylbenzothiophene and benzoylhydrazone, resp. In the case of 3-methylbenzothiophene, however, the [2+2] cycloadduct VIII is formed, together with 2-benzoyl-3-methylbenzothiophene. In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6Related Products of 36748-88-6).
