Cross‐Metathesis of Terminal Alkynes

Chemistry – A European Journal, 2014
AbstractTerminal acetylenes are amongst the most problematic substrates for alkyne metathesis because they tend to undergo rapid polymerization on contact with a metal alkylidyne. The molybdenum complex 3 endowed with triphenylsilanolate ligands, however, is capable of inducing surprisingly effective cross‐metathesis reactions of terminal alkyl ...

Two-directional cross-metathesis

Organic & Biomolecular Chemistry, 2009
Two-directional cross-metathesis of a range of alpha,omega dienes with a variety of electron deficient alkenes has been accomplished. It was found that the process is quite general and gives complete selectivity for the E,E-dienes, making this a very useful and high yielding protocol for two-directional chain elongation.

Alkenol−Alkyne Cross Metathesis

Organic Letters, 2008
Allyl alcohols and their homologues were used in the enyne cross metathesis to prepare hydroxy-functionalized dienes. An isomerization was found to occur under prolonged heating, and a method for conversion to ( E)-diene product is also reported.

Synthesis of Vinyl‐Functionalized Thiazoles by Cross‐Metathesis and Tandem Stille Coupling/Cross‐Metathesis

Advanced Synthesis & Catalysis, 2007
AbstractThe application of olefin cross‐metathesis to vinyl‐functionalized thiazoles and the tandem Stille coupling/cross‐metathesis of bis‐trifloylthiazoles are reported. These processes offer new opportunities for the synthesis of complex natural products.

Olefin Cross-Metathesis

2007
Olefin cross-metathesis has become an indispensable tool for efficient carbon–carbon bond formation. Fundamental studies on functional group tolerance and an understanding of the steric and electronic factors crucial to product selectivity have led to the development of an empirical model for reaction design.
