Abstract: The thermal decomposition of 2-pyrrolidinone and 2-pyrrolidinethione was investigated in a flow system by following the changes in their UV photoelectron spectra at various temperatures. At ca. 850°C 2-pyrrolidinone begins to decompose by a decarbonylation process into carbon monoxide, ethene, hydrogen cyanide and molecular hydrogen. By contrast, at ca. 800°C, 2-pyrrolidinethione decomposes mainly into pyrrole and hydrogen sulfide. MO calculations at the PM3 and 6-31G levels provide theoretical support for the mechanisms proposed for these decompositions.
