Summary
-
1.
The kinetically controlled stages of NH exchange and of Z, E-isomerization of the nitroenamines studied have a common transition state that includes a molecule of the reactant and a pyridine molecule.
-
2.
For the enamines studied, a pseudomonomolecular mechanism of NH exchange in an aprotic solvent has been observed.
