Kiselev, E. Kashaeva, M. Shihab, M. Medvedeva, A. Konovalov] The partial molar volumes (V) and the enthalpies of dissolution (Δdis H) for tetracyanoethylene, cyclopentadiene, and their Diels—Alder adduct were determined at 25°C. Eleven solvents of the π- and n-donor type were used. The use of alkylbenzenes as solvents for tetracyanoethylene induces pronounced changes in the enthalpy of dissolution (up to 26 kJ mol−1) and in the partial molar volume (up to 11 cm3 mol−1), whereas these parameters for the adduct change slightly. TheV and Δdis H values for cyclopentadiene virtually do not depend on the nature of the solvent. In the case of tetracyanoethylene and the adduct in n-donor solvents, considerable variations of theV and Δdis H values are observed; they are not linear functions of the change in the partial molar volume of the adduct. Therefore, the reaction volumes in acetonitrile (−40.69) and ethyl acetate (−45.56) differ sharply from those ino-xylene (−24.28) and mesitylene (−21.76 cm3 mol−1).
