Paracyclophanes in Action: Asymmetric Catalytic Dialkylzinc Addition to Imines Using [2.2]Paracyclophane-based N,O-Ligands as Catalysts

Paracyclophanes in Action: Asymmetric Catalytic Dialkylzinc Addition to Imines Using [2.2]Paracyclophane-based N,O-Ligands as Catalysts

The asymmetric addition of dibutylzinc to imines is achieved by employing [2.2]paracyclophane‐based ketimine ligands with good to excellent enantioselectivities. A comparison to other organozinc reagent is made.
