Synthesis of in-situ surfactant-free Pd nanoparticle catalysts for the synthesis of aromatic azo compounds and for unsaturated bond hydrogenation by hydrogen transfer

We developed a simple and efficient method to synthesize aromatic azos by hydrogen transfer using palladium(II) acetylacetonate as a catalyst and isopropyl alcohol as a hydrogen source. Furthermore, this system also showed catalytic potential for the hydrogenation of carbonyl groups or C=C bonds with yields up to ∼97%.

A simple and efficient method to synthesize aromatic azos by hydrogen transfer has been developed. Pd(acac)2 was selected as a catalyst and isopropyl alcohol was selected as the hydrogen source. This system also works well for the hydrogenation of unsaturated compounds containing a carbonyl group or C=C bond with yields up to ∼97%.Figure optionsDownload as PowerPoint slide
