Synthesis and reactivity of molybdenum imido alkylidene bis-pyrazolide complexes.
Reaction of Li(3,5-R(2)-pyrazolide) (R = tBu or Ph, dXpz) with Mo(NAr)(CHCMe(2)Ph)(OTf)(2)(DME) yields Mo(NAr)(CHCMe(2)Ph)(dXpz)(2) in good yield. These complexes react with alcohols or the surface silanols of silica, to yield bis-alkoxy and surface mono-siloxy alkene metathesis catalysts, respectively.
متن کاملSalicylaldimine Ruthenium Alkylidene Complexes: Metathesis Catalysts Tuned for Protic Solvents.
Tuning the electronic and steric environment of olefin metathesis catalysts with specialized ligands can adapt them to broader applications, including metathesis in aqueous solvents. Bidentate salicylaldimine ligands are known to stabilize ruthenium alkylidene complexes, as well as allow ring-closing metathesis in protic media. Here, we report the synthesis and characterization of exceptionally...
متن کاملAlkyne-Protected Ruthenium Nanoparticles†
Stable ruthenium nanoparticles protected by 1-octynyl fragments were synthesized by a wet chemical method. Transmission electron microscopic measurements showed that the resulting particles exhibited an average core diameter of 2.55 ( 0.15 nm with well-defined Ru crystalline lattice fringes. Because of the formation of RusCt bonds, the CtC vibrational stretch was found in FTIR measurements to r...
متن کاملThermal properties of ruthenium alkylidene-polymerized dicyclopentadiene
Differential scanning calorimetry (DSC) analysis of ring opening methatesis polymerization (ROMP) derived polydicyclopentadiene (PDCPD) revealed an unexpected thermal behavior. A recurring exothermic signal can be observed in the DSC analysis after an elapsed time period. This exothermic signal was found to be proportional to the resting period and was accompanied by a constant increase in the ...

Vinylidene complexes [Ru(η(5)-C5H5){[double bond, length as m-dash]C[double bond, length as m-dash]C(H)R}(PPh3)L]BPh4 (, ) [L = P(OMe)3, P(OEt)3; R = Ph, p-tolyl, Bu(t), H] react with hydrazine R1NHNH2 (R1 = H, Me, Ph) to afford nitrile derivatives [Ru(η(5)-C5H5)(N[triple bond, length as m-dash]CCH2R)(PPh3)L]BPh4 (, ) and amine R1NH2. Hydroxylamine NH2OH also reacts with vinylidenes , to yield ...
