摘要： A catalytic method is provided for a ring-opening cross-metathesis reaction between a cycloolefinic substrate and a second olefinic reactant, wherein the catalyst used is a transition metal alkylidene complex substituted with an N-heterocyclic carbene ligand. The substrates are selected so that the rate of the cross-metathesis reaction of the second olefinic reactant, kCM, is greater than or equal to the rate of the ring-opening metathesis reaction, kRO. In this way, the predominant ROCM product is a monomer, dimer, and/or oligomer, but not a polymer. The invention additionally provides for selective production of an end-differentiated olefinic product, using trisubstituted cycloolefins as substrates and/or a subsequent cross-metathesis reaction following an initial ROCM step. The cycloolefinic substrates include low-strain olefins such as cyclohexene as well as higher strain olefins such as cyclooctene.

摘要： A process is described for carrying out olefin oligomerisation in two catalysis steps of different types, using an organic feed containing at least one olefin. The cut to be treated, containing at least one olefin (Cn), is introduced into a first reaction zone where, in a first step, it undergoes catalytic oligomerisation either of the homogeneous liquid phase type, or of the heterogeneous type with a solid support. The effluent produced is generally sent to a heat exchanger traversed by a cold liquid, the effluent thus being cooled before being sent to a second reaction zone where it undergoes catalytic oligomerisation in a liquid-liquid two-phase medium, the invention being characterized in that at least an ethylenic hydrocarbon containing 3 to 5 carbon atoms per molecule is added to the inlet to the second reaction zone.

摘要： A process of dehydrating acetaldehyde to produce ethyne comprising passing acetaldehyde in the gas phase over a dehydration catalyst such as aluminum oxide which may be promoted with mercuric sulfate at a temperature of approximately 600 degrees Centigrade to produce ethyne and water and a cooling zone following the reaction zone. This method having the advantage of ease of separation of ethyne from the unreacted acetaldehyde and co-product water by simple condensation whereby the ethyne remains gaseous while the other compounds liquify and is thereby separated in essentially pure form.

摘要： The novel two-stage process described here makes it possible to obtain substituted benzyl compounds and toluene derivatives in a simple manner and in high yields by means of Suzuki-type coupling reactions of an aromatic with an organoboron compound, followed by a reduction. The process is particularly useful for preparing ortho-substituted benzyl compounds and toluene derivatives. The process can be applied to both intermolecular and intramolecular coupling reactions. Catalysts used for the coupling reaction are palladium compounds and/or nickel compounds. An advantageous aspect is that only very small amounts of catalyst are required.
