Conclusions

  1. 1.

    We have prepared palladium complexes anchored to amino-containing silica gels that are active in the hydrogenation of C-C bonds and of the C=N bonds of Schiff bases.

  2. 2.

    In the presence of a palladium complex linked to silica gel containing γ-aminopropyl groups the double bonds hydrogenated stepwise and selectively: cyclopentadiene to cyclopentene, methylcyclopentadiene to methylcyclopentene, dimethylethynylcarbinol to dimethylvinylcarbinol, and Schiff bases to secondary amines.

  3. 3.

    Palladium complexes on supports modified with aminomethyl and tert-aminomethyl groups are unstable and are reduced by hydrogen, liberating palladium metal.
