Conclusions
Photoionization was used to determine the appearance potentials of ions from 2-acetylfuran, 2-acetylthiophene, 2-acetylpyrrole, 2,5-dimethylfuran, 2,5-dimethylthiophene, and 2,5-dimethylpyrrole. The enthalpies of formation were determined for RC≡0+ ions (R=2-furyl, 2-thienyl, and 2-pyrroloyl), pyrilium, and thiopyrilium ions.
