Thermal Decomposition of Ions. 1. Pyrolysis of Protonated Ethers. Activation Energies and A Factors

Unimolecular rate constants (kd) have been measured at the high-pressure limit for the thermal decomposition of protonated dimethoxyethane (glyme) and bis(2-methoxyethyl)ether (diglyme).In both cases the decomposition involves loss of CH3OH and formation of an oxycarbonium ion.The variation of kd with temperature gives log A=11.1 and Ea=21.1 kcal*mol-1 for the pyrolysis of (glyme)H+ and log A=13.7 and Ea=30.7 for (diglyme)H+.To the best of our knowledge these are first Arrhenius parameters ever determined for the decomposition of cations in the vapor phase under equilibrium conditions at the high-pressure limit.The data and thermochemistry are consistent with a transition state in which electron shifts result in the disruption of an internal hydrogen bond.
