Abstract
The proton NMR spectra of several N‐acetyl‐N‐methyl polynitroanilines reveal the presence of two conformers. The conformer ratio has been studied for the picrylaniline in various solvents, and the rate of conformer interchange for this substance was measured in 1,4‐dioxane. Chemical‐shift studies of these and various related molecules have given additional information about the configuration of these molecules. It is concluded that the acetamide group is normal to the plane of the aromatic ring for the N‐acetyl‐N‐methyl‐2,4,6‐trinitro and 2,6‐dinitro anilines.Keywords
