    • 31b diameter of ether, benzene, dioxane, and THF are very similar (see Supporting Information). The diameters of acetonitrile and methylbutane are slightly smaller. However, these two solvents have very small quadrupole moments.

    • note
    • The data indicate that the entropy contribution to ΔG, -TΔS, is less positive for 2 than for 1 in acetonitrile at 300 K. This result is surprising. Although there is no thermodynamic significance to the ratio of two entropies, it is interesting to note that ΔS(2)/ΔS(1) decreases with increasing solvent polarity: the ratios (± 0.1) are 1.4 in diethyl ether, 1.3 in dioxane, 1.1 in THF, and 0.9 in acetonitrile.

    • 35c posited a vertical electron affinity in acrylonitrile of -0.1 eV and in fumaronitrile of 1.8 eV. Cross conjugation involving the two nitrile groups in 1 and the presence of the alkyl ring should produce an EA that is between 0 and 1 eV.
