Abstract: A heterogeneous and enantioselective hydrogenation catalyst is developed, by anion exchange of sulfonated Ru-BINAP ([2,2'-Bis(diphenylphosphino-1,1'-binaphtyl]chlorobenzene-ruthenium (II)) chloride on the external surface of Layered Double Hydroxides (LDH). It is found by XRD that the binap-complex is only present at the outer surface and is not intercalated within the interlamellar space of the clay. The immobilized complex catalyses the hydrogenation of geraniol with good enantioselectivity. However, deactivation of the catalyst could not be avoided. The heterogeneous hydrogenation of dimethyl itaconoate proceeds at comparable rates and enantioselectivities than the homogeneous system, not showing deactivation. Leaching of the BINAP complex from the LDH surface was found to be absent in all cases.
