The invention relates to a process for the preparation of a deuterated ethanol from ethanol, D.sub.2O, a ruthenium catalyst, and a co-solvent.

The present invention addresses to a process for producing olefins and esters in the C10 to C13 range from fatty acid esters through a catalytic hydrogenation reaction followed by cross-metathesis of the hydrogenated product with light olefins.

A functionalized magnetic nanoparticle including an organometallic sandwich compound and a magnetic metal oxide. The functionalized magnetic nanoparticle may be reacted with a metal precursor to form in a catalyst for various CC bond forming reactions. The catalyst may be recovered with ease by attracting the catalyst with a magnet.

The present invention relates to a method for the reductive amination of a carbonyl compound, comprising one or more carbonyl groups amenable to reductive amination, forming the corresponding primary amine, characterized in that the reaction is carried out in the presence of a homogeneously dissolved catalyst complex K, comprising at least one metal atom from Group 8, 9 or 10 of the periodic table, bearing a bidentate phosphane ligand, a carbonyl ligand, a neutral ligand and a hydride ligand, and also an acid as co-catalyst.

Disclosed herein are processes, systems, and reaction systems for the oligomerization of ethylene to form an ethylene oligomer product in a reaction zone using a catalyst system having i) a chromium component comprising a heteroatomic ligand chromium compound complex of the type disclosed herein, and ii) an aluminoxane. A C.sub.3+ olefin can be present in the reaction zone for a period of time, where the C.sub.3+ olefin is not an ethylene oligomer formed in-situ within the reaction zone.

The invention relates to a process for preparing 1,3-butadiene by means of ene-yne metathesis over at least one transition metal catalyst of the element ruthenium.

Methods for preparing the Bruton's Tyrosine Kinase (BTK) inhibitor compound 2-{3-hydroxymethyl-1-methyl-5-[5-((S)-2-methyl-4-oxetan-3-yl-piperazin-1-yl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-[3,4]bipyridinyl-2-yl}-7,7-dimethyl-3,4,7,8-tetrahydro-2H,6H-cyclopenta[4,5]pyrrolo[1,2-a]pyrazin-1-one are provided. Methods for preparing tricyclic lactam compounds are also provided.

A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex; combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe.sub.3O.sub.4-nanoparticle-supported ferrocenyl phosphine catalyst.

A functionalized magnetic nanoparticle including an organometallic sandwich compound and a magnetic metal oxide. The functionalized magnetic nanoparticle may be reacted with a metal precursor to form a catalyst for various CC bond forming reactions. The catalyst may be recovered with ease by attracting the catalyst with a magnet.

The invention concerns a catalytic composition comprising: at least one nickel precursor with an oxidation number of (+II) containing a phosphine ligand complexed with nickel, at least one Lewis base, and at least one activating agent selected from the group formed by chlorinated and brominated hydrocarbylaluminium compounds, used alone or as a mixture, in a manner such that the molar ratio of the ensemble of the Lewis base and phosphine ligand complexed with the nickel of the composition to the nickel is in the range 5 to 30. The invention also concerns the use of said catalytic composition.
