摘要:
The temperature and concentration dependence of1H NMR chemical shifts of pentafluoroaniline and aniline in acetone (Ac), dimethylsulphoxide (DMSO) and hexamethylphosphortriamide (HMPA) indicate that the effect of hydrogen bond formation, δ = δobs- δA' is similar for both anilines. The analysis of1H NMR spectra showed, that proton exchange of t-butyl alcohol (tBA) and 2,6-di-t-butylphenol (DTBPh) with pentafluoroaniline is slower than that with aniline.
