LiClO4 catalyses the addition of CHCl2CO2H to olefins (cyclopentene cycloheptene and trans-cyclo-octene). Specific salt effects are discussed in terms of general acid catalysis. This mechanism is supported by the linear relation: log kex = - αHo + β. Solvent isotope effects show a slow proton transfer. Eyring parameters are determined; ΔS* < 0. These experiments are consistent with a mechanism involving carbocation formation as the slow step. © 1974.
