A water-soluble ruthenium-based olefin metathesis catalyst supported by a poly(ethylene glycol) conjugated N-heterocyclic carbene ligand is reported. The catalyst displays greater activity in aqueous ring-opening metathesis polymerization (ROMP) reactions than previously reported water-soluble metathesis catalysts.
To mark the occasion of Prof. W. J. (Jim) Feast's official retirement, an international symposium was held in Durham on July 16th and 17th 2004. This article, written by some of the participants in that symposium, highlights the contributions that Jim Feast has made in the areas of ring-opening metathesis polymerisation, electroactive polymers and dendrimers and hyperbranched polymers. In particular,...
