报告摘要:

Molecular Metal Catalysts allow the selective transformations of a variety of simple and non toxic substrates under mild conditions, low energy with atom economy. Some of the catalytic processes can

-be performed in non toxic solvents such as water, or

-take place with atom economy

-be applied to give added value to renewable molecules.

Ruthenium catalysts which are easy to make, stable in air and often in water, and not too costly are in the heart of these clean and mild processes.

 

Three examples illustrating the Rennes research in catalysis will be presented.

 

Ruthenium (Cp*Ru) activation of alkynes for selective C-O and C-C bond formation: From ruthenium-vinylidenes to alkylidene species, via alkyne oxidative addition or carbene precursors and for Selective Syntheses of functional dienes and bicyclic products.

 

Alkene metathesis alkylidene-ruthenium catalysts are key promoters for selective transformations of terpenes and for Alkylidene-Ruthenium Cascade catalyses: alkene metathesis/hydrogenation for biomass transformations into polyamides.

 

Ruthenium(II) activation of C-H bonds allow C-C bond cross couplings in water : Rennes has established the mechanism of C-H bond activation by deprotonation with Ru(II) and carboxylate partners. Many applications were discovered for catalytic synthesis of polyfunctional molecules, polyfunctional alkenes and alkylation of phosphine oxides as precursors of new functional phosphine ligands.
