Description
Summary:Azairidacycles derived from protic benzylamines have been utilized as powerful hydrogen‐transfer catalysts for ketones and alcohols. The chiral amidoiridium complexes are accessible from (R)‐5‐amino‐6,7,8,9‐tetrahydro‐5H‐benzocycloheptene and (R)‐1‐phenyl‐2,2‐dimethylpropylamine, whereas O‐silylated (S)‐2‐amino‐2‐phenylethanols afford amido‐bridged dimers. The preferable catalytic performance of the mononuclear complexes corroborates that the 16‐electron structure is vital for the smooth H+/H– transfer based on the metal/NH cooperative effect.
