摘要：

Low energy barriers for rotation about carbon-carbon double bonds were discovered in various substituted 1-carbomethoxyacrylonitriles. Rotational rates were found to be within the nmr time scale, and activation energies were determined by variable temperature studies. Thermodynamic as well as kinetic properties of the exchanging diastereomers were investigated by the varying of structural parameters. © 1969, American Chemical Society. All rights reserved.
