Abstract

Structure of metal complex catalysts for olefin metathesis reaction and its mechanism are intensively studied since many years. Most of catalytic systems involve tungsten complexes combined with alkyl aluminium compound, WCl6/C2H5A1C12. The currently accepted mechanism is based on carbene complex formation which next coordinates olefins in such a way that the metallocycle may be formed with high selectivity. However, the formation of the first carbene is still controversial. Highly active metathesis catalysts have been prepared only with Mo, W or Re soluble complexes. So, there is also some limitation to the metal. If metal carbonyls are used as catalyst precursors they are often activated photochemically or by addition of Lewis acid type cocatalysts.
