Notes:
The 13C NMR chemical shift values of (aryl)(2-nitrobenzo[b]thiophen-3-yl)amines were measured in DMSO-d6 solutions, suggesting the occurrence of an alternate charge polarization at C-3, C-2, C-3a, C-7a, C-4 and C-5. A dual substituent parameter analysis of the experimental data indicates a large or a low resonance contribution for aryl para or meta substituents, respectively, while the inductive component remains constant throughout.
