Abstract

The dynamics of the hydride-ion transfer reaction between CH⁺ ₃ (or CD⁺ ₃) and C₂H₆ was investigated in a crossed-beam scattering experiment at the collision energy of 1.7 eV (c.m.). Formation of an osculating intermediate complex of a mean lifetime of about 1 ps was inferred from the scattering data. The reaction of CD⁺ ₃ leads to the ion products C₂H⁺ ₅ and C₂H₂D⁺ ₃ formed practically without H, D scrambling. The mechanism of the process is viewed as a formation of a protonated propane intermediate which decomposes from its critical configuration (CH₃HCH₂CH₃)⁺ by splitting off a neutral methane molecule on either one or the other end with respect to the reactant ion attack.
