Catalytic systems with extension ' service life and maintenance for the metathesis of olefins.

摘要

Catalytic systems improved a long time, comprising initially: is a compound of the tungsten; b organometallic compound, an organic compound which is partially or completely fluorinated. p / p process of stabilization of these catalytic systems, comprising the solution of a in an organic solvent, in contact with a stirring and heating to between 0 and 100 c. for 0,5 to 60 minutes, then introducing the mixture of a and b. / p & & p & application of these catalytic systems stabilized at the metathesis of olefins carrying functional groups or do not carry such groups.
