It hinges on the ligand : The electron‐donor ability of NiN 2 S 2 ligands is compared to that of traditional diphosphine and diimine ligands. Structural comparison of NiN 2 S 2 and o ‐phenanthroline (phen) complexes of {W(CO) 4 } and {PdX 2 } units shows asymmetry imposed by the hinge bonding of the NiN 2 S 2 S donors (see superimposed structures) which favors stereo‐ and regioselective substrate addition.
