Resumen:
SiO2-supported bimetallic and organobimetallic PtSn catalysts were prepd. by surface organometallic chem. on metals and tested in the hydrogenation of different carbonyl compds. [RCHO (R = Pr, Ph), EtCOMe, cyclohexanone, R1CH:CHCHO [R1 = Me, Ph (I)]]. The influence of the Sn/Pt at. ratio on I hydrogenation was studied, yielding an optimum value of ∼0.4. The selective hydrogenation of the C=O group in polyfunctional mols. was explained on the basis of a combination of geometric (specially in organobimetallic catalysts), and electronic effects due to the presence of ionic Sn.
