Making metathesis plus nanofiltration POSS-ible: New molecular-weight-enlarged metathesis catalysts, which bear polyhedral oligomeric silsesquioxane (POSS) tags, have been synthesized and characterized. The catalysts can be recovered from the reaction mixture by using nanofiltration techniques and can be reused. The membranes Starmem 228 and PuraMem 280 can be used to successfully separate the catalyst from the post-reaction mixtures.
