Controlled Distribution of Solid Catalysts into Two Immiscible Liquid Phases – Synthesis and Catalytic Applications
A new concept for the separation of heterogeneous catalysts is presented. Against gravity, surface modified catalysts are located only in one of two immiscible liquid phases. The catalyst phase can be separate...

Heck Reactions of Aryl Chlorides Catalyzed by Ligand Free Palladium Salts
Palladium acetate has been shown to be a highly active catalyst for Heck reactions of aryl chlorides even in the absence of organic ligands. Bromobenzene can efficiently be coupled in presence of negligible tr...

Increased Conversion in the Heck Reaction Under Irradiation with Light
Irradiation with light (UV–vis and visible) was shown to increase the rate of the Heck reaction at 90–140 °C using both heterogeneous and homogeneous catalysts. The photoreduction of Pd(II) is most likely the ...

Catalytic Properties of a Novel Raney-Nickel Foam in the Hydrogenation of Benzene
The catalytic properties of a novel Raney-Nickel mold were investigated in the liquid-phase hydrogenation of benzene and compared to commercially available Raney-Nickel. The novel Raney-Nickel catalyst showed ...
