The influence of temperature on the rate of dehydrochlorination of 3-chloro-3-methylbut-1-ene in 17 aprotic and 13 protic solvents, ν = k[C 5H9Cl], was studied by the verdazyl method. In aprotic solvents, the electrophilicity, ionizing power, and cohesion of solvents decrease ΔG ≠ by increasing ΔS ≠. The nucleophilicity and polarizability increase both ΔH ≠ and ΔS ≠ to equal extent and therefore do not affect ΔG ≠. In protic solvents, the solvent nucleophilicity increases ΔH ≠ to a greater extent than ΔS ≠, and the overall effect of the nucleophilic solvation is small and negative.

The kinetics of 3-methyl-3-chloro-1-butene solvolysis at 25°C in MeOH, EtOH, BuOH, i-BuOH, PentOH, 2-PrOH, 2-BuOH, HexOH, OctOH, t-BuOH, t-PentOH, cyclohexanol, and allyl alcohol was studied by the verdazyl method; v = k[C 5H9Cl], SN1 + E1 mechanism. The reaction rate shows a satisfactory correlation with the parameter of the solvent ionizing power E T and is independent of the solvent nucleophilicity. 2005 Pleiades Publishing, Inc.
