A process of metathesizing a feedstock in the presence of a metathesis catalyst and at least one catalyst enhancer. The catalyst enhancer can be selected from a sacrificial catalyst or a non-catalyst enhancer. The process exhibits improved reaction times and/or the metathesis catalyst can be used at very low concentrations.
