We report the development of ruthenium-based metathesis catalysts with chelating N-heterocyclic carbene (NHC) ligands that catalyze highly Z-selective olefin metathesis. The nomenclature R i,i+3 S(8) refers to an eight-carbon metathesized cross-link with R-configuration at i and S-configuration at i+3 position 17; S i,i+4 S(8), 8.

Ring-opening metathesis polymerization (ROMP) uses metathesis catalysts to generate polymers from cyclic olefins. Independently synthesized in 2000 by the Hoveyda and Blechert groups, this catalyst has become commonly known as the 2 nd Generation Hoveyda (or Hoveyda-Grubbs… Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double.
