The rate constants of solvolyses of 2,2,2-trichloro-1,1-dimethylethyl chloroformate ($underline{I}$) in 33 solvents can be well correlated using the extended Grunwald-Winstein equation, with incorporation of the $N_T$ solvent nucleophilicity scale and the $Y_{Cl}$ solvent ionizing scale, with sensitivities towards changes in the scale having values of $1.42;{pm};0.09$ for l and $0.39;{pm};0.05$ for m, respectively. The activation enthalpies are ${Delta}H^{ eq};=;12.3$ to $14.5;kcal{cdot}mol^{-1}$ and the activation entropies are -28.2 to $-35.5;cal{cdot}mol^{-1}{cdot}K^{-1}$, consistent with the proposed bimolecular reaction mechanism. The kinetic solvent isotope effect of 2.14 in MeOH/MeOD is in accord with a bimolecular mechanism, probably assisted by general-base catalysis.
