An NCN pincer palladium complex was developed as a probe molecule to index the coordination ability of various monodentate ligands. Coordination constants of 27 monodentate ligands (L) with a pincer palladium complex to form complexes of the type ArPd(L)2Cl were determined by 1H NMR spectroscopy. This allowed the coordination ability of a wide variety of ligands, including P-coordinating ligands (phosphane, phosphite), as well as As-coordinating AsPh3, and N-coordinating pyridine, to be indexed. The differential between the highest/lowest coordination constants was 10 12. The relative coordination ability is described in a logarithmic manner, log(Keq(L)/Keq(PPh3)), with respect to the value of PPh3 to exhibit high linearity in the Hammett plot.
