Abstract

Two types of tungsten phenoxide catalysts have been synthesized; viz. {A figure is presented} and {A figure is presented}, respectively. When associated with C₂H₅AlCl₂, these precursor complexes exhibit a fair and an extremely high catalytic activity for A and B respectively. Within each series there is a relationship between activity and stereoselectivity, the most active catalysts being those which are the least stereoselective with a limiting value of unity for the trans/cis ratio of the products. The results are explained on the basis of a simple theory which correlates the activity and the stereoselectivity with the respective energy levels of the metallacyclobutane complex and of the metallacarbene-olefin complex.
