PNP-type pincer ligands with aliphatic backbones were a focal point in this respect. A synthetic methodology for the preparation of related organometallic compounds was developed, giving access to diverse Mo(0), Mo(I) and Mo(II) compounds. The reported complexes were subsequently applied for the catalytic hydrogenation of ketones, styrenes, N-methylated formanilides as well as aromatic and aliphatic nitriles.
