Alkyne metathesis by molybdenum and tungsten alkylidyne complexes.
نویسنده
چکیده
Alkyne metathesis by molybdenum and tungsten alkylidyne complexes is now ~45 years old. Progress in the practical aspects of alkyne metathesis reactions with well-defined complexes, as well as applications, in the last decade, guarantees that it is destined to become a useful method for the synthesis of organic molecules.

Recent advances in the development of alkyne metathesis catalysts
The number of well-defined molybdenum and tungsten alkylidyne complexes that are able to catalyze alkyne metathesis reactions efficiently has been significantly expanded in recent years.The latest developments in this field featuring highly active imidazolin-2-iminato- and silanolate-alkylidyne complexes are outlined in this review.
متن کاملZ-Selective Olefin Metathesis Processes and Cis/Syndioselective ROMP with High Oxidation State Molybdenum Alkylidenes
Chapter 1 Reaction of W(CCMe 3)Cl 3(dme) with one equivalent of (3,5-Me 2C6H3NCH 2CH 2)3N)Li3 affords yellow, crystalline W(CCMe 3)(N3N) in good yield. The reactivity of this new alkylidyne complex towards terminal alkynes was investigated. Two other new tungsten alkylidynes, W(CCMe 3)(pyr) 3 (pyr = 2,5-dimethylpyrrolide) and W(CCMe3)(Ph 2N)3 were prepared by the addition of three equivalents o...
متن کاملAlcohol-promoted ring-opening alkyne metathesis polymerization.
Alcohol is the answer! An inactive, air-stable, dimeric molybdenum alkylidyne complex is activated toward ring-opening alkyne metathesis polymerization (ROAMP) by the addition of methanol. The ROAMP is compatible with water and phenol-containing substrates and with the in situ photochemical generation of alkyne monomers from cyclopropenones.
متن کاملEndo-selective enyne ring-closing metathesis promoted by stereogenic-at-W mono-pyrrolide complexes.
The utility of W-alkylidene complexes for enyne ring-closing metathesis is demonstrated in a direct comparison with Mo-based analogs. Tungsten complexes lead to less alkyne oligomerization and higher levels of endo-selectivity and enantioselectivity.
متن کاملPractical new silyloxy-based alkyne metathesis catalysts with optimized activity and selectivity profiles.
Triphenylsilanolate ligands were found to impart excellent reactivity and outstanding functional group tolerance on molybdenum alkylidyne complexes, which catalyze alkyne metathesis reactions of all sorts. The active species either can be obtained in high yield by adaptation of the established synthesis routes leading to Schrock alkylidynes or can be generated in situ from the molybdenum nitrid...
