Building Indenylidene–Ruthenium Catalysts for Metathesis Transformationsby the large number of applications for natural product synthesis. Among the numerous catalysts developed to mediate olefin metathesis transformations, ruthenium–indenylidene complexes are robust and powerful pre-catalysts. The discovery of this catalyst category was slightly muddled due to a first

Ruthenium Catalysts Bearing Carboxylate Ligandsis catalysts is discussed. New catalytic system due to high affinity to silica gel allow to efficient catalyst removal to obtain colorless products with low ruthenium contamination. Unique structural motif allows to introduce new carboxylate and sulfonate derived ligands without use of silver or th

Ruthenium—Arene Complexes Derived from NHC∙CO2 and NHC∙CS2 Zwitterionic Adducts and Their Use in Oleorresponding N-heterocyclic carbenes (NHCs) with either carbon dioxide or carbon disulfide. All the zwitterionic products were characterized by various analytical techniques, including thermogravimetric analysis (TGA). Their ability to act as NHC ligand precursors for in situ catalytic applications

Mesoporous Molecular Sieves Based Catalysts for Olefin Metathesis and Metathesis Polymerizationa as supports are reported. The catalysts were prepared either by spreading of transition metal oxidic phase on the support surface or by immobilizing transition metal compounds (mostly organometallic) on the support. The activity of these catalysts in various types of metathesis reactions (i.e. alk

Functionalisation of Vinylsubstituted (Poly)Siloxanes and Silsesquioxanes via Cross-Metathesis and Sing with acetylenes for functionalisation of vinylsubstituted (poly)organosiloxanes were overviewed. Cross-metathesis and silylative coupling of olefins with vinylsilicon compounds catalysed by ruthenium complexes were shown to constitute two valuable, complementary synthetic routes leading to funct

The Olefin Metathesis Reactions in Dendrimerslly results from our group are reviewed here. Dendrimers have been loaded at their periphery with ruthenium-chelating bis-phosphines, which leads to the formation of dendrimer-cored stars by ring-opening-metathesis polymerization (ROMP). CpFe.-induced perallylation of polymethylaromatics (Cp = η5-C.
