Additive free: Hydrotalcite‐supported silver nanoparticles act as a highly efficient heterogeneous catalyst for the dehydrogenation of diverse alcohols (see picture) in the absence of any acceptors such as molecular oxygen, hydrogen peroxide, or unsaturated organic compounds. The solid Ag catalyst was readily reusable without any loss of activity and selectivity.

Ohne Zusätze: Silbernanopartikel auf Hydrotalcit‐Trägern wirken hoch effizient in der heterogenkatalysierten Dehydrierung von Alkoholen (siehe Bild), wobei auf Akzeptoren wie molekularen Sauerstoff, Wasserstoffperoxid oder ungesättigte organische Verbindungen verzichtet werden kann. Der Katalysator kann ohne Aktivitäts‐ und Selektivitätsverlust wiederverwendet werden.

Dehydrogenation O 0212Oxidant-Free Alcohol Dehydrogenation Using a Reusable Hydrotalcite-Supported Silver Nanoparticle Catalyst. -The highly atom-efficient and reusable Ag-hydrotalcite system allows the heterogeneous dehydrogenation of primary and secondary alcohols under oxidant-and additive-free conditions with coproduction of equimolar amounts of H2. Compared to the Ru and Pd species, Ag-hydrotalcite shows the highest chemoselectivity compared to hydrogen transfer or isomerization. -(MITSUDOME, T.; MIKAMI, Y.; FUNAI, H.; MIZUGAKI, T.; JITSUKAWA, K.; KANEDA*, K.; Angew.
