NEW RUTHENIUM CATALYSTS FOR ALKENE METATHESIS

摘要

The main developments in ruthenium catalyst design for alkene metathesis covering the last 4 years is presented. These new catalysts are essentially based on modifications brought to Grubbs- or Hoveyda-type catalysts and the generation of catalysts by activation of propargyl derivatives leading to ruthenium-allenylidene, -indenylidene, and alkenylcarbene catalysts.
