Efficient Removal of Ruthenium Byproducts from Olefin Metathesis Products by Simple Aqueous Extraction
Simple aqueous extraction removed ruthenium byproducts efficiently from ring-closing metathesis (RCM) reactions catalyzed by a poly(ethylene glycol) (PEG) supported N-heterocyclic carbene-based ruthenium complex.
