Kinetic chlorine isotope effects attending the solvolysis of several ring-substituted 1-phenylethyl chlorides in alcohol–water solvent mixtures are reported. The k35/k37 values are insensitive to the identity of ring substituents and to solvent composition. Results are interpreted in terms of an SN1 heterolytic process incorporating a significant amount of internal return. Theoretical calculations suggest that the incipient chloride ion in the transition state may be strongly hydrogen-bonded.

Experimental Values

Three empirical equations are proposed to fit the experimental values of the dissociation constant for picric acid, chosen as guide-solute working in the N, N-dimethylformamide/2-methoxyethanol solvent system. The work was performed operating at 19 temperatures ranging from − 10 to + 80 °C in the pure solvents and in their nine mixtures, identified by the mole fraction (X) of one component. This empirical treatment, which describes the dependence of the dissociation constant on temperature and composition of the solvent mixture, is represented by functions of the type K = K(T), K = K(X), and K = K(T, X). The K = K(T, X) equation in its complete form is composed of 20 terms, some of which can be eliminated because of small statistical weight; the number and type of these terms vary on passing from one solvent system to another and the best-fitting form is suggested. A comparison among various K = K(T, X) equations proposed in the present and in previous works has been made. Key words: dissociation equilibria, binary nonaqueous solvent mixtures, picric acid, N,N-dimethylformamide, 2-methoxyethanol.

Dipolar Aprotic Solvents

The rates of reaction of methyl iodide with chloride ion in some protic-dipolar aprotic solvent mixtures have been measured. The rate-retarding effect of protic solvents at M concentration in dimethylacetamide is in the order p-NO2C6H4OH > C6H5OH > C6H5SH > C6H5CO2H ≈ CH3OH > C6H5NH2 >H2O ≈ D2O. Protic solvents slow the reaction by a general rather than a specific hydrogen bonding interaction with the anion. Both the dipolar aprotic solvent and the protic solvent, as well as the anion, accept hydrogen bonds, and this influences the interaction between protic solvent and anion.
