The barrier to rotation about the benzylic bond in α-cyano-α-methoxybenzyl radical was determined to Ea = 9.8 +/- 0.8 kcal/mol (log A = 12.6 +/- 0.5) by ESR line-shape analysis in the temperature range from 30 to 80 deg C.Comparison with known and estimated rotational barries in α-monosubstituted benzyl radicals indicates for this radical no special captodative stabilization which exceeds the additivity of the substituent effects.

The differences in enthalpy and entropy between meso- and DL-2,3-dimethoxy-2,3-diphenylsuccinonitrile (2) were deduced from the equilibrium constants of their interconversion at elevated temperatures via reversible dissociation into α-cyano-α-methoxybenzy
