A new highly efficient ruthenium metathesis catalyst
Wakamatsu, Hideaki,Blechert, Siegfried
, p. 2403 - 2405 (2002)
Olefin metathesis even at 0°C! A phenyl substituent in the ruthenium catalyst 2 leads to greatly increased initiation rates in different metathesis reactions, for example, the cyclization of 1 to form 3.

Paragraph 0099, (2014/08/19)
Cis and trans ruthenium complexes that can be used as catalysts for ring opening metathesis polymerisation (ROMP) are described. The complexes are generally square pyramidal in nature, having two anionic ligands X. Corresponding cationic complexes where one or both of the anionic ligands X are replaced by a non-co-ordinating anionic ligand are also described. Polymers such as polydicyclopentadiene (PDCPD) can be prepared using the catalysts.
Supported ruthenium-carbene catalyst on ionic magnetic nanoparticles for olefin metathesis
Chen, Shu-Wei,Zhang, Zhi-Cheng,Ma, Miaofeng,Zhong, Chong-Min,Lee, Sang-Gi

The Grubbs-Hoveyda ruthenium-carbene complex has been covalently immobilized on ionic magnetic nanoparticles utilizing an imidazolium salt linker. The supported catalyst exhibited excellent catalytic activity for ring-closing metathesis (RCM) and cross-me
Mixed N-heterocyclic carbene/phosphite ruthenium complexes: The effect of a bulkier NHC.
Urbina-Blanco, Cesar A.,Bantreil, Xavier,Wappel, Julia,Schmid, Thibault E.,Slawin, Alexandra M. Z.,Slugovc, Christian,Cazin, Catherine S. J.
supporting information, p. 6240 - 6247 (2013/12/04)
The synthesis, characterization, and catalytic activity of two new complexes, 2a,b, featuring a sterically demanding NHC and two different phosphites are described. Complexes 2a,b display a mutually trans arrangement of the π-acidic phosphite and the strong σ-donor SIPr ligand (SIPr = N,N′-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene). The synergy between the phosphite and the NHC ligand was revealed in the RCM of challenging substrates leading to tetrasubstituted olefins where, in comparison to their phosphine-containing analogues, 2a,b allowed higher conversions of these challenging substrates.
