isomerization of primary allylic alcohols to chiral aldehydes using iridium‐catalysts bearing P,N‐MaxPHOX ligands has been studied. These catalysts can be fine‐tuned as they present three different stereogenic centers to modulate both the reactivity and enantioselectivity of a family of different substrates. The experimental part is supported by a DFT study of the reaction mechanism, which provides new

We report here the catalytic isomerization of aryl-substituted allylic alcohols mediated by lanthanide alkoxide complexes. The conversion yields allylcarbinols as the products of the olefin isomerization process, but with different olefinic positions than those afforded by typical transition metal catalysts. The average isolated product yields in these reactions are 65–81%. The catalytic cycle and
