Sol-gel immobilized catalyst systems for tandem transformations with trans-stilbene as an intermediate

Abstract

Tandem catalytic systems containing one or two sol-gel immobilized catalysts were successfully applied in the synthesis of trans-stilbene oxide and 1,2-diphenylethane. The catalysts were prepared from palladium and/or manganese precursors in the presence of orthosilicates using a sol-gel method and could be reused several times successfully.
