Abstract

W(CO)₅L (L = CO, PPh₃, P(OPh)₃, P(n-C₄H₉)₃) associated with C₂H₅AlCl₂ and molecular oxygen is a highly active metathesis catalyst for acyclic olefins. An infrared investigation of the interaction between the catalytic components indicates firt an acid-base interaction leading to a sol1 1 adduct {A figure is presented} identified with L ≠ CO which is not stable and gives rise to dissociation of the ligand L and formation of the unsaturated zerovalent species W(CO)₅. Oxidation to W(CO)₄Cl₂ then occurs according to a stoichiometry which remains unknown. Mass equilibrium indicates also the formation of non-carbonyl complexes of tungsten, which might be highly unsaturated zerovalent tungsten or highly oxidized tungsten, such as WOCl₂ or WCl₄.
