AbstractIsomerizing olefin metathesis is currently undergoing a transformation from laboratory curiosity to powerful synthetic concept at the heart of orthogonal tandem catalysis. In this process, an isomerization catalyst continuously moves double bonds along carbon chains, while a metathesis catalyst scrambles the residues at the C−C double bonds ...

AbstractAccording to popular belief, oxygen and water are the natural enemies of organometallic reactions and therefore must be excluded rigorously from the reaction vessel. This belief is founded in the case of the highly reactive nucleophilic metal alkylidene complexes that were used in early catalytic olefin metathesis.

Sustainable Concepts in Olefin Metathesis
Angewandte Chemie - International Edition, 2007AbstractRuthenium‐catalyzed olefin metathesis reactions represent an attractive and powerful transformation for the formation of new carbon–carbon double bonds. This area is now quite familiar to most chemists as numerous catalysts are available that enable a plethora of olefin metathesis reactions.

Olefin metathesis in carotenoid synthesis
Organic & Biomolecular Chemistry, 2009Olefin metathesis is a powerful and widely applicable synthetic method for carbon-carbon double bond formation. However, its application to the synthesis of conjugating polyene chains has been very limited because of possible undesired side reactions. We attempted to apply this method to the synthesis of symmetrical carotenoids.

An artificial metalloenzyme for olefin metathesis
Chemical Communications, 2011A Grubbs-Hoveyda type olefin metathesis catalyst, equipped with an electrophilic bromoacetamide group, was used to modify a cysteine-containing variant of a small heat shock protein from Methanocaldococcus jannaschii. The resulting artificial metalloenzyme was found to be active under acidic conditions in a benchmark ring closing metathesis reaction.
