The invention relates to tungsten oxo alkylidene complexes ligated with a tetraphenylphenoxy ligand and a neutral ligand such as a phosphine or a pyridine, and method of making the complexes. The complexes are useful as catalysts for performing a ring-opening metathesis polymerization of dicyclopentadiene to poly(dicyclopentadiene).
