Proton NMR spectra were recorded and analysed for 1‐bromo‐4‐nitrobenzene, 2‐bromo‐5‐nitroluene, 3‐bromo‐6‐nitrotoluene and 2‐bromo‐5‐nitro‐p‐xylene, as well as for the corresponding compounds having p‐CH3C6H4S in place of Br. Chemical shifts and coupling constants generally agree with expected values; however, a deshielding effect of the methyl group on aromatic protons was observed in one case.

Abstract
Proton NMR spectra were recorded and analysed for 1‐bromo‐4‐nitrobenzene, 2‐bromo‐5‐nitroluene, 3‐bromo‐6‐nitrotoluene and 2‐bromo‐5‐nitro‐p‐xylene, as well as for the corresponding compounds having p‐CH3C6H4S in place of Br. Chemical shifts and coupling constants generally agree with expected values; however, a deshielding effect of the methyl group on aromatic protons was observed in one case.File in questo prodotto:
