Barriers to the amide rotation in mercapto-N,N-dialkylbenzamides and some of their derivatives were measured by dynamic 1H NMR.For N,N-diisopropylamides, barriers to rotation about carbonyl-aryl bond were also determined.The results show that the intramolecular hydrogen bond has only a very small influence on the measured barriers.In contrast to the literature data, only one set of signals, common to all possible forms of 2-mercapto-N,N-dimethylbenzamide, has been observed.
