which deserves further cownent. Examination of the data presented by the authors o; the above-mentioned communication indicates that the a have failed to differentiate between two unrelated pheonomena which led them to misleading conclusions.
This fact can best be demonstrated by data of our own which serves to clarify the matter.

The substantial effect of polar substituents on barriers to rotation about S-N bonds in substituted arenesulfenamides, X-C6H4SWR8R", has been attributed to (p-d)n conjugation between nitrogen and sulfur.' However, no such effect has been observed on barriers to syn, anti interconversion in N-alkylid
## Abstract The molecule __N__,__N__‐dimethylacetoacetamide, which is subject to a keto–enol equilibrium process in solution, also exhibits hindered rotation about the amido NC bond. The hindered rotation rates have been studied by lineshape fit methods of the nuclear magnetic resonance spectra. I
