Abstract

The applicability of 2D EXSY NMR spectroscopy for studying quantitatively the dynamic behaviour in three aroylcyanoketene‐S, S‐dimethylacetals was tested by means of ^1^H NMR spectroscopy. It can be concluded that the method is a reasonable qualitative supplement to complete line‐shape analysis.

Using 1D and 2D NMR spectra, the compounds obtained, in a mixture, in the reaction of glycerol with iodine were identified as the two isomers (cis and trans) of 2-iodomethyl-5-hydroxymethyl-1,4-dioxane and the two isomers (cis and trans) of 2-iodomethyl-6-hydroxymethyl-1,4-dioxane. Thus, the composi
