Abstract:

Hemilabile ligands possessing two or more donor atoms with very different electronic properties close to the metal represent a very active research field. The binding of the metal to a chelating ligand containing hard and soft donor atoms allows for the easy displacement of the labile group providing access to an open coordination site in a reversible manner. These features make hemilabile ligands very interesting in a number of fields including coordination chemistry and metal complex catalysis. The current work presents a comprehensive study on the synthesis of novel phosphinamide bidentate ligands 3a-c employing directed ortho-lithiation methodology (Scheme 1) and subsequent complexation with zinc chloride.
