摘要：

A detailed study of enamines substituted (H2NC(H)=C(H)R) by an electron acceptor group (R = NO2, CN, CHO) in solution has been performed by using the self-consistent reaction field (SCRF) approach. The solvent effects on the E-Z equilibrium as well as on the barriers to internal rotation are in agreement with the known experimental data. Consideration of the electronic wave function allows a detailed analysis of the solvent effects. The polarization of the solute under the influence of the solvent as well as the modifications of its geometry are far from being negligible. Preliminary attempts to estimate electron correlation effects have also been evaluated, and they appear less important than the former effects.
