Resumen:
As part of our ongoing studies on the
preparation of bimetallic catalysts derived from chiral organometallic
compounds in order to use them in heterogeneous catalysis, we consider it
of interest to carry out the preparation of bimetallic systems derived from
chiral organogermanium compounds and Pt supported on SiO2.
Bimetallic systems were prepared by controlled surface reactions, using
techniques derived from the Surface Organometallic Chemistry on Metals (SOMC/M). A key step in the preparation of asymmetric heterogeneous catalysts based
on silica-supported platinum chemically modified with chiral organometallic
compounds is the synthesis of optically pure organometallic derivatives.
In this
contribution, we report the enantioselective hydrogenation of acetophenone
using a catalytic system composed of Pt modified with
tri-(-)-menthylmethylgermanium and tri-(‑)-menthylgermanium hydride.
