Menthane‐Based Chloride‐Bridged η 3 ‐Bis‐π‐Allylpalladium Chloride Dimers: Catalytic Asymmetric Allylation of Imines

Menthane‐based η 3 ‐bis‐π‐allylpalladium chloride dimer complexes have been prepared for the first time. They exist as dimeric η 3 ‐bis‐π‐allylpalladium with four chloride bridges. The complexes catalyze the asymmetric allylation of various imines with allyltributylstannane and one equivalent of water to give chiral homoallylamines in yields of 60–77 % and enantioselectivity up to er = 93:7. The stereochemical information from the menthane framework was translated successfully through the η 3 ‐bis‐ π ‐allylpalladium catalysts in asymmetric allylation of imines.
