Significance

In this communication the authors report on a synthetic route to enantio- and dia­stereomerically pure dimeric ferrocenyl bispalladacycles. Those complexes nicely complements the previous work of the authors on the Overman rearrangement of tri­fluoroacetimidates (Angew. Chem. Int. Ed. 2006, 45, 5694-5698) and expand it to Z-substrates.
