• Ion-molecule reactions of CF3+ with propyne, allene, and 1-butyne have been studied at near-thermal energies (~0.05 eV) by using an ion-beam apparatus. Initial product ion distributions and reaction rate constants were determined. For propyne and allene, major product channels were electrophilic addition followed by HF and CF2 elimination and a minor product channel was a hydride abstraction reaction. For 1-butyne, major product channels were electrophilic addition followed by C2H2F2, C2H3F, and 2HF eliminations. The reaction rate constants were (1.5±0.1), (0.40±0.05), and (1.6±0.1)×10-9 cm3s-1 molecule-1 for propyne, allene, and 1-butyne, respectively.
