Influence of stereoelectronic interactions on the 13C NMR chemical shift in iodine-containing molecules
Methyl substitution in ortho position causes a deshielding of 6–7 ppm on the 13C NMR chemical shift of the own methyl group and the carbon nucleus bonded to iodine atom (ipso) in iodobenzene-like molecules. In contrast, the carbon ipso is 3–4 ppm shielded when methyl is in para. To understand how th...
