The specific rates of solvolyis of methyl chloroformate are very well correlated by the extended Grunwald–Winstein equation over a wide range of solvents; the pathway is believed to be predominantly addition–elimination, except that a positive deviation for solvolysis in 90% 1,1,1,3,3,3-hexafluoropropan-2-ol suggests an 80% contribution from an ionisation mechanism.
