Reactions of C5H3+ and C5H5+ Ions with Acetylene and Diacetylene

Abstract

The reactions of C5H3+ and C5H5+ ions with acetylene and diacetylene were investigated using a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer. The ejection capabilities of FTICR were used to determine the reaction mechanisms and rate constants for the reactions of ions produced from a number of precursors. While different structures could be attributed to C5H3+ ions produced from different precursors on the basis of reactivity, this could not be done for C5H5+ ions, whose reactivity was similar regardless of precursor. Different percentages of reactive C5H5+ structure(s) were produced from various precursors using several charge transfer gases. Formation of C5H5+ from norbornadiene and cycloheptatriene was studied in more detail and existence of a second formation mechanism was shown to be possible. Results are discussed in relation to previous work involving C3H3+ and C5H5+ reactions and a proposed ionic route to soot formation.
