Qualitative Picture

The kinetic parameters for hindered rotation about the C—N bond have been determined by total nuclear magnetic resonance line shape analysis for the methyl esters of N,N-dimethyldithiocarbamic acid, and N,N-dimethylmonothiocarbamic acid. A qualitative picture of the effect of substituents on the potential barrier in carbamate and thiocarbamate esters is presented.
