Grubbs catalyst metathesis
Olefin Metathesis ~Well-Defined Ru Catalysts~ 3rd Literature Seminar August 5, 2013 Soichi Ito (M2) 1. This catalyst is commonly known as the 2 nd Generation Grubbs Catalyst, and along with the 1 st Generation Grubbs Catalyst is one of the most widely-used. A General Model for Selectivity in Olefin Cross Metathesis Arnab K Chatterjee, Tae-Lim Choi, Daniel P Sanders, and Robert H Grubbs* Contribution from the Arnold. 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) Catalyst.
Enyne Metathesis The Enyne Metathesis Using the second generation Grubbs' catalyst, the reaction is believed to involve an initial reaction with the alkene. The first-generation Grubbs catalyst, while largely replaced by the second-generation catalyst in usage, was not only the first catalyst to be developed.

Nina Notman describes the dance of olefin metathesis, and how the tempo is set by Grubbs’ catalysts. Ring closing metathesis by Hoveyda–Grubbs catalysts: For the Hoveyda–Grubbs catalyst, however, there are few publications.
