Ethylene-promoted versus ethylene-free enyne metathesis
Grotevendt, Anne G. D.,Lummiss, Justin A. M.,Mastronardi, Melanie L.,Fogg, Deryn E.
, p. 15918 - 15921 (2011)
The role of ethylene in promoting metathesis of acetylenic enynes is probed within the context of ring-closing enyne metathesis, using first- and second-generation Grubbs catalysts. Under inert atmosphere, rapid catalyst deactivation is observed by calibr
N-heterocyclic carbene and phosphine ruthenium indenylidene precatalysts: A comparative study in olefin metathesis
Clavier, Herve,Nolan, Steven P.
, p. 8029 - 8036 (2008/03/14)
Kinetic studies on ring-closing metathesis of unhindered and hindered substrates using phosphine and N-heterocyclic carbene (NHC)-containing ruthenium-indenylidene complexes (first and second generation precatalysts, respectively) have been carried out. T
Hybrid-bridged silsesquioxane as recyclable metathesis catalyst derived from a bis-silylated Hoveyda-type ligand
Elias, Xavier,Pleixats, Roser,Man, Michel Wong Chi,Moreau, Joel J. E.
, p. 751 - 762 (2007/10/03)
The synthesis of a bis-silylated Hoveyda-type monomer is described as well as the preparation of several organic-inorganic hybrid materials derived from it by a sol-gel process (with and without tetraethyl orthosilicate) and by anchoring to MCM-41. The re
A new cycloisomerisation catalyst of enynes: One-step synthesis of 3,4- dialkylidenetetrahydrofurans from allyl propargyl ethers
le Paih, Jacques,Rodríguez, Darío Cuervo,Dérien, Sylvie,Dixneuf, Pierre H.
, p. 95 - 97 (2007/10/03)
The precatalyst RuCl(cod)C5Me5 in the presence of acetic acid or ethanol allows the selective one-step cycloisomerisation of allyl propargyl ethers into 3,4-dialkylidenetetrahydrofurans.
Catalytic synthesis of 3-vinyl-2,5-dihydrofurans from yne-enes promoted by photochemically activated metal-allenylidene LnRu=C=C=CR2 complex
Picquet, Michel,Bruneau, Christian,Dixneuf, Pierre H.
, p. 2249 - 2250 (2007/10/03)
The ruthenium(II)-allenylidene salt [(p-cymene)(PCy3)-ClRu=C=C=CPh2]PF6 acts as an olefin metathesis catalyst precursor for the yne-ene transformation of the mixed propargylic allyl ethers HC=C-CR2OCH2/sub
