Carbonyl–Olefin Metathesis

Chemical Reviews, 2021
This Review describes the development of strategies for carbonyl-olefin metathesis reactions relying on stepwise, stoichiometric, or catalytic approaches. A comprehensive overview of currently available methods is provided starting with Paternò-Büchi cycloadditions between carbonyls and alkenes, followed by fragmentation of the resulting oxetanes ...

Aqueous Olefin Metathesis

Angewandte Chemie International Edition, 2008
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.

Isomerizing Olefin Metathesis

Chemistry – A European Journal, 2019
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 ...

1,5-Enyne Metathesis

Journal of the American Chemical Society, 2008
Enyne metathesis reactions on 1,5-enyne substrates are described, using Grubbs−Hoveyda II catalyst and under microwave irradiation:  Cyclobutenes have been obtained in low to fair yields (19−58%).
