ABSTRACT:
Improved process of metathesis of olefins by contact of one or more olefins with a catalyst comprising a tungsten complex with two phenoxy groups, carrying substituents and four other ligands, the complex carrying as coordination groups a halogen atom, an alkyl radical and a carbene. The catalyst preferably is of the formula ##STR1## where X is halogen, R is hydrocarbon or an electronegative group or atom, R.sup.1 is alkyl and R.sup.2 and R.sup.3 are individually hydrogen or alkyl groups.
