摘要
The potential surface of conformational transitions of O-vinylacetoxime was studied and the regions of “starting” states for possible isomeric transformations with the N—O bond dissociation as the limiting stage were recognized. The activation parameters and heat effects of intramolecular rearrangement O-vinylacetoxime → iminoacetaldehyde were evaluated. Transition-state structure of the rearrangement was identified.
