Abstract
The potential surface of conformational transitions of O-vinylacetoxime was Studied and the regions of "starting" states for possible isomeric transfo rmations with the N-O bond dissociation as the limiting stage were recogniz ed. The activation parameters and heat effects of intramolecular rearrangem ent O-vinylacetoxime --> iminoacetaldehyde were evaluated. Transition-state structure of the rearrangement was identified.
