Abstract
AbstractThe rates of proton transfer and hydrogen atom abstraction between ionized enols [CH2CHOH]+˙ and [CH2C(CH3)OH]+˙ were measured by Fourier transform ion cyclotron resonance Spectrometry. It was observed that proton transfer is favoured by its high rate even when it does not reach the limiting collision rate. When a competition is in principle possible between H+, H˙ and H− transfers, only the former process is observed. This phenomenon and the low efficiency of hydrogen atom abstraction are discussed in terms of the potential energy profile, where the stability of the intermediate complexes plays a critical role.
