  8. Representative Examples of the Metathesis of n-hexane

  9. The Mechanism of Metathesis and Dehydrogenation Goldman, A. S. et. al. J. Am. Chem. Soc. 1999, 121, 4087

  10. The Reason of Decomposition

  11. The Metathesis by Ir-based Catalysts and Re2O7/Al2O3

  12. Conclusions • The decomposition of the olefin metathesis catalysts appears to limit conversions. • The author also expect that more active dehydrogenation catalysts will give more turnovers before decomposition of the metathesis catalyst.
