N2 - The intramolecular CH activation of a diphenylphenoxy ligand by an electrophilic WVI center is the crucial step in the synthesis of the extremely active and stereoselective metathesis catalyst 1 formed from [WCl3(CCMe3)(dme)] or [WCl4(O‐2,6‐C6H3Ph2)2]. In the metathesis of ethyl oleate, replenishing of the catalyst is not required; 500 moles of substrate per mole of 1 are converted in one hour at 25°C. (Figure Presented.)
