Development of N-vinylsulfonamide-based olefin-metathesis catalysts. a Representative Ru-based olefin-metathesis catalysts have limited initiation or propagation properties in ROMP at low temperatures. b The development of N-vinylsulfonamide-based metathesis catalysts. c Comparison of the initiation rates of Ru-based olefin-metathesis catalysts. The kinit values were determined by reacting a catalyst with 30 equiv. of butyl vinyl ether (BVE) at 10 °C in toluene (0.1 mM)
