| Abstract: | Analysis and Optimization of Gasphase Reactions, XVII. — Selenoketene The thermal decomposition of 1,2,3-selenadiazole in the gaseous phase has been investigated by photoelectron and mass spectroscopy. At temperatures above 720 K selenoketene is formed, the PE spectrum of which can be assigned based on ab initio SCF calculations as well as on radical cation state comparison with the iso(valence) electronic heterocumulenes H2C ? C ? O and H2C ? C ? S. The 4-phenyl derivative decomposes above 820 K forming phenylacetylene. |
