experimental part, p. 1838 - 1842 (2011/04/15)
Reactions of acetyl iodide with pyridine at room temperature and with quinoline both at 20-25°C and on cooling to -50°C involve dehydrohalogenation of acetyl iodide with formation of ketene and pyridinium or quinolinium iodides. The reaction of acetyl iodide with pyridine at -5 to -50°C led to the formation of N-acetylpyridinium iodide. Benzoyl iodide reacted with both pyridine and quinoline at both -50°C and at 20-25°C to form stable N-benzoylpyridinium and N-benzoylquinolinium iodides. The reaction of pyrrole with acetyl iodide under analogous conditions was accompanied by polymerization. Pleiades Publishing, Ltd., 2010.

The thermal decomposition of thiirane and 2-methylthiirane was investigated in a flow system by following the changes in their photoelectron spectra at various temperatures.Similar decomposition patterns were observed in both cases.Thus at 600 deg C, formation of sulfur and an alkene was detected.At higher temperatures, conversion of thiirane into ethenethiol and thioacetaldehyde, and of 2-methylthiirane into cis- and trans-prop-1-ene-1-thiol was observed.Hydrogen sulfide, alkynes, carbon disulfide and thiophene were detected as products of secondary reactions.The experimental data pertaining to the rearrangement processes are compared with potential energy profiles, calculated by using the MNDO/CHAIN procedure.A mechanism involving initial C-S bond breaking, followed by 1,2-hydrogen shift, is suggested by the results.
