The title compounds were prepared by the reaction of the corresponding N ‐2‐hydroxyisopropylanilines with thionyl chloride in the presence of triethylamine, and their pmr and cmr spectra were examined. On the basis of the chemical shifts due to the γ‐ and δ‐effects, the stereochemical structures are discussed.
