Abstract

Nothing to sm(Ir)k at: Under appropriate reaction conditions, iridium hydride catalysts promote the isomerization of primary allylic alcohols. The best catalysts, like (R)‐1 (P green, O red, N blue, Ir yellow), deliver the desired chiral aldehydes with excellent enantioselectivity and good yields. Mechanistic hypotheses have been developed on the basis of preliminary investigations.magnified image

## Abstract **Unter sehr milden Reaktionsbedingungen** vermitteln Iridiumhydridkatalysatoren die Isomerisierung primärer Allylalkohole. Die besten Katalysatoren, darunter (__R__)‐**1**, liefern die gewünschten chiralen Aldehyde mit ausgezeichneten Enantioselektivitäten und in guten Ausbeuten. Auf d
