Abstract

original image

Ironing it out: The simple pre-catalyst system FeCl3/EtMgCl was applied to the hydrogenation of various alkenes and alkynes at room temperature. Domino iron-catalyzed allylation/hydrogenation reactions were performed under 1–4 bar H2. Spectroscopic studies determined the heterogeneous nature of the active catalyst species, its oxidation state (Fe0), and the local structure and size of the formed particles.
