An immobilised grubbs 2nd generation catalyst for application in flow-through devices
Gmeiner, Julia,Seibicke, Max,Lang, Carolin,Gaertner, Ute,Trapp, Oliver
, p. 2081 - 2087 (2014)
An improved immobilised Grubbs 2nd generation catalyst and its application in flow-through devices, shown for on-column reaction gas chromatography (ocRGC), has been studied. The coupling of a reaction capillary and a separation column in GC/MS
Alkynyl-functionalized imidazolium for "click" dendrimer functionalisation and palladium nanoparticle stabilization
Deraedt, Christophe,D'Halluin, Martin,Lesturgez, Stephanie,Salmon, Lionel,Goglio, Graziella,Ruiz, Jaime,Astruc, Didier
, p. 1345 - 1350 (2015)
Functionalization of imidazolium salts (IMSs) that allow easy derivation of molecular or solid supports are called for in various applications. Here, the synthesis of an alkyne-containing IMS can be achieved in three steps from 2,4,6-trimethylaniline, and

Six olefin metathesis catalysts, based on a common ruthenium precursor featuring a hydroxy-substituted N-heterocyclic carbene ligand, were successfully prepared and fully characterised. As proof-of-concept, two of them ([Ru]isonico and [Ru]sub
Ruthenium olefin metathesis catalysts featuring n-heterocyclic carbene ligands tagged with isonicotinic and 4-(Dimethylamino)benzoic acid rests: Evaluation of a modular synthetic strategy
Czarnocki, Stefan,Monsigny, Louis,Sienkiewicz, Micha?,Kajetanowicz, Anna,Grela, Karol
, (2021/09/06)
A modular and flexible strategy towards the synthesis of N-heterocyclic carbene (NHC) ligands bearing Br?nsted base tags has been proposed and then adopted in the preparation of two tagged NHC ligands bearing rests of isonicotinic and 4-(dimethylamino)benzoic acids. Such tagged NHC ligands represent an attractive starting point for the synthesis of olefin metathesis ruthenium catalysts tagged in non-dissociating ligands. The influence of the Br?nsted basic tags on the activity of such obtained olefin metathesis catalysts has been studied.
Self-supported oligomeric grubbs/hoveyda-type Ru - Carbene complexes for ring-closing metathesis
Chen, Shu-Wei,Kim, Ju Hyun,Song, Choong Eui,Lee, Sang-Gi
, p. 3845 - 3848 (2008/02/12)
On the basis of the release-return metathesis mechanism, self-supported oligomeric Grubbs/Hoveyda-type Ru-carbene complexes have been designed and synthesized as a new type of recoverable catalyst for ring-closing metathesis. The catalytic activities of t
Synthesis of a silica-based heterogeneous second generation grubbs catalyst
Mayr, Monika,Buchmeiser, Michael R.,Wurst, Klaus
, p. 712 - 719 (2007/10/03)
The synthesis of a second generation Grubbs catalyst immobilized onto non-porous silica is described. For this purpose, a polymerizable cationic NHC precursor, 1,3-bis(1-mesityl)-4-{[(bicyclo[2.2.1]hept-5-en-2-ylcarbonyl)oxy] methyl}-4,5-dihydro-1H-imidaz
