- Telomerisation of 1,3-butadiene with 1,4:3,6-dianhydrohexitols: An atom-economic and selective synthesis of amphiphilic monoethers from agro-based diols
-
The telomerisation of 1,3-butadiene with a Pd/TPPTS catalytic system in water or an organic solvent was used for the synthesis of C8 ethers from isosorbide, an agro-based diol. The use of water/oil biphasic reaction conditions allowed the selective synthe

- Liquid-phase isomerization of saturated and unsaturated epoxides
-
The liquid-phase isomerization of a variety of epoxides was studied using a complex catalyst system based on magnesium bromide and dimethylformamide. The data obtained elucidate the mechanism of the liquid-phase isomerization and show the range of oxygen-containing compounds which can be prepared through this reaction.

- Imidazolium salts and the use of these ionic liquids as a solvent and as a catalyst
-
New 1,2,3- or 1,2,3,4- or 1,2,3,4,5- substituted imidazolium salts and their uses as solvent in catalyzed organic reactions, as well as compositions containing them and a transition metal compound. They can be used in the following reactions : the telomerisation of conjugated dienes, the dimerisation of olefins, the oligomerisation of olefins, the polymerization of olefins, the alkylation of olefins, the hydrogenation of olefins, the olefin metathesis, the hydroformylation of olefins, the ring-closing metathesis of olefins, the ring-opening metathesis polymerisation of olefins, the symetric or asymetric epoxidation of olefins (including heteroatom substituted olefins) and the cyclopropanation of olefins, the condensation reaction, the hydrogenation reaction, the isomerization reaction, the Suzuki cross-coupling reactions, the amination reaction, the partial oxidation of alkancs, the kinetic resolution of racemic mixtures, the hydrogenation of imines, the hydrogenation of ketones, the transfer hydrogenation and the hydroxylation of aromatic organic compounds.

- Process of telomerizing conjugated dienes
-
The present invention is related to a process for telomerizing a conjugated diene which comprises reacting said conjugated diene with a compound containing active hydrogen in the presence of a catalyst system comprising at least one transition metal compound, at least one phosphorus-containing compound, and at least one salt which forms a liquid under the conditions of the telomerization process.
