The present invention relates to novel ruthenium-based triazole carbene complexes comprising specific ligands, their preparation and their use as catalysts in hydrogenation processes. Such complex catalysts are inexpensive, thermally robust, gel formation inhibiting and olefin selective.

Ruthenium-based triazole carbene complexes

A metallocene complex I, II, III and IV, 

Boron-bridged 2-indenyl metallocene complexes for olefin polymerization

The present invention relates to novel Ruthenium-based complex compounds which represent viable catalysts, in particular for all sorts of metathesis reactions. Such complex compounds can be prepared by a novel, very favorable and cost efficient method which includes the introduction of an alkylidene ligand into the complex by using vinyl sulfides or vinyl ethers.

Ruthenium-based complexes, their preparation and use as catalysts

The present invention provides novel Ruthenium-based transition metal complex catalysts comprising specific ligands, their preparation and their use in hydrogenation processes. Such complex catalysts are inexpensive, thermally robust, and olefin selective.

Ruthenium-based complex catalysts

The present invention provides stable, cyclic bent allene metal complexes and methods of conducting chemical processes, preferably olefin hydrogenation, comprising contacting an olefin substrate, preferably an unsaturated polymer, with a cyclic bent allene metal complex as described herein, under hydrogenation conditions.

Cyclic bent allene metal complexes

Novel transition metal complexes are provided which represent viable catalysts for a broad variety of reactions such as hydrogenation reactions and metathesis reactions. Novel preparation processes are made available via unprecedented routes inter alia not involving structures according to Grubbs I or Grubbs II catalysts.

Transition metal complexes, their preparation and use

The invention relates to a metallocene complex according to the following formula (1) 

Bis(2-indenyl) metallocene complex
