“…In solution, many of these ions are formed at low temperature in strong acid solutions, and the carbocations have frequently been characterized by NMR. − In the gas phase, the reactions of carbocations produced by electron impact on hydrocarbons have been studied extensively . Small hydrocarbon cations are also found in flames, and highly unsaturated ions have been detected in interstellar clouds …”

The potential energy surface for C4H5 + as calculated by ab initio molecular orbital theory is reported at two levels of theory, HF/6-31G(d,p) and MP2(full)/6-311G(d,p). Fourteen minima have been located at HF/6-31G(d,p), but inclusion of electron correlation reduced this number to nine. The methylcyclopropenyl cation, 1, is the global minimum, and the 2-cyclobutenyl (2), α-vinylvinyl (3), γ-methylpropargyl (4), α-methylpropargyl (5), and 1-cyclobutenyl (6) cations are 9.1, 19.9, 25.3, 27.5, and 26.9 kcal/mol, respectively, above 1. Eleven transition structures, permitting interconversion between the nine minima, are reported. Enthalpies of formation (in kcal/mol) calculated at MP4SDTQ/6-311++G(2df,p) are 231.4 for 1, 241.7 for 2, 246.9 for 3, 255.7 for 5, 259.9 for 6, and 264.3 for 7.

A kinetic study of the chemiluminescence of the emitters CH(A2Δ), C2(d3Πg) and C2H* in a mixture of acetylene, oxygen and hydrogen atoms has been performed using a low pressure discharge flow reactor at 2.66 mbar and 298 K under largely varying initial conditions. The absolute concentrations of the emitters could be quantitatively simulated and correlated to the simultaneous formation of higher hydrocarbons in this system when the following formation reactions of the excited species are assumed These reactions are in particular accord with the dependence of the chemiluminescence on the concentration of free hydrogen atoms.
