Objectives

Develop new supported catalysts for continuous flow asymmetric hydrogenation by immobilizing chiral catalysts (metallic complexes and nanoparticles) on the surface of nanostructured carbon materials (carbon nanotubes and/or graphene) [1-3]. An innovative aspect with the supported nanoparticles will be to take advantage of the strong effect of carbonaceous supports in the activation of hydrogen and of the specific metal-single layer graphene interaction [3, 4]

Expected Results

Achieve a new generation of highly active (TOF ≥ 1000 h-1) and selective catalysts (ee ≥ 95%) in asymmetric hydrogenation of C=C and C=N benchmark substrates. Determine the structure/activity relationships of these catalysts through a rational optimization of the anchoring process taking into account the influence of the nature of the support/catalyst interactions. Rationalization of enantioselectivity in relation with both the substrates, substituents, and the solvent.
