Organogermanium compounds anchored on Pt/SiO2 as chiral catalysts for the enantioselective hydrogenation of 3,4-hexanedione

This work reports the synthesis of PtGe chiral catalysts using organogermanium compounds containing (−)-menthyl groups as substituents. Chiral inducers were carefully synthesized and characterized in order to obtain optically pure compounds.PtGe catalysts were prepared through a controlled surface reaction between the supported transition metal and the organometallic compound. This technique leads to reproducible and well defined phases. The...
