Wray, Victor et al. published their research in Organic Magnetic Resonance in 1977 | CAS: 64248-57-3

1,2-Difluoro-3-iodobenzene (cas: 64248-57-3) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.SDS of cas: 64248-57-3

The additivity of substituent effects upon J(FF) in polysubstituted fluorobenzenes: an update was written by Wray, Victor;Lincoln, David N.. And the article was included in Organic Magnetic Resonance in 1977.SDS of cas: 64248-57-3 This article mentions the following:

Substituent constants nJFF values (n = 2-5) and calculated unperturbed couplings are reported for 1,2,3-, 1,2,4-, 1,3,2-, 1,3,4-, 1,3,5-, and 1,4,2-F2RC6H3 (R = NH2, OH, F, Cl, Br, I, CF3, CN, NO2). Substituent effects on 3JFF values are additive. A previous anal. (Abraham, R. J.; MacDonald, D. B.; Pepper, E. S., 1968) of 4JFF and 5JFF is updated. In the experiment, the researchers used many compounds, for example, 1,2-Difluoro-3-iodobenzene (cas: 64248-57-3SDS of cas: 64248-57-3).
