Zusammenfassung
Rates of internal rotation around carbonyl-to-nitrogen bonds are determined for the rotamers IA and IB of N-benzyl-N,2,4,6-tetramethylbenzamide by equilibration of IA and for N,N,2,4,6-pentamethylbenzamide (II) by 1H-NMR line shapes. The activation parameters (Table V) obtained by the two methods agree well within error limits. This represents the first experimental confirmation of the soundness ...
