Application of a Grubbs-Hoveyda metathesis catalyst noncovalently immobilized by fluorous-fluorous interactions
Michalek, Florian,Bannwarth, Willi
, p. 1030 - 1037 (2006)
A Grubbs-Hoveyda metathesis catalyst bearing a tris(perfluoroalkyl)silyl tag for efficient noncovalent attachment to fluorous silica gel (FSG) was synthesized and employed in ring-closing metathesis (RCM) reactions in CH 2Cl2. After
A recyclable 'boomerang' polymer-supported ruthenium catalyst for olefin metathesis
Ahmed, Mahmood,Barrett, Anthony G. M.,Braddock, D. Christopher,Cramp, Susan M.,Procopiou, Panayiotis A.
, p. 8657 - 8662 (1999)
Polymer supported ruthenium catalyst 8 was found to be an effective catalyst for ring closing metathesis. The rate of reaction and activity was found to be comparable to that of homogeneous catalyst 1. In addition, the catalyst could be recycled and re-us
Activation of olefin metathesis complexes containing unsymmetrical unsaturated N-heterocyclic carbenes by copper and gold transmetalation
Kamal, Fadwa,Colombel-Rouen, Sophie,Dumas, Adrien,Guégan, Jean-Paul,Roisnel, Thierry,Dorcet, Vincent,Baslé, Olivier,Rouen, Mathieu,Mauduit, Marc
, p. 11583 - 11586 (2019)
The activation of ruthenium-indenylidene complexes containing two unsymmetrical unsaturated N-heterocyclic carbenes (u2-NHCs) by a transmetalation process is reported. The use of copper(i) or gold(i) chlorides promotes the rapid trapping of one NHC ligand, which releases the catalytically active Ru-species. Impressive initiation rates with full-conversions are observed within one minute. This practical protocol demonstrates excellent catalytic performances in various ring-closing metathesis (RCM) and self-metathesis (SM) reactions.
Silylcyclopropanes by Selective [1,4]-Wittig Rearrangement of 4-Silyl-5,6-dihydropyrans
Mori-Quiroz, Luis M.,Maloba, Emmanuel W.,Maleczka, Robert E.
, p. 5724 - 5728 (2021/07/31)
4-Silyl-5,6-dihydropyrans undergo remarkably selective [1,4]-Wittig rearrangements to give silylcyclopropanes in good yields. The selectivity is independent of the silyl group, but it is influenced by the electronic character of the migrating center. Elec

Olefin metathesis is now one of the most efficient ways to create new carbon-carbon bonds. While most efforts focused on the development of ever-more efficient catalysts, a particular attention has recently been devoted to developing latent metathesis cat
