Syntheses and Properties of Palladium Complexes Containing Phosphorus−Nitrogen−Phosphorus Ligands with a Tunable Hemilabile Site

A series of phosphorus−nitrogen−phosphorus (PNP) ligands of the type R−N(CH2CH2PPh2)2 (R = C(O)(C6H4OMe-p), t Bu, Ph, C6H4OMe-p) have been prepared. Their coordination chemistry to palladium(II) and palladium(0) complexes was examined using a combination of X-ray crystallography, NMR, and electroch...

description A series of phosphorus−nitrogen−phosphorus (PNP) ligands of the type R−N(CH2CH2PPh2)2 (R = C(O)(C6H4OMe-p), t Bu, Ph, C6H4OMe-p) have been prepared. Their coordination chemistry to palladium(II) and palladium(0) complexes was examined using a combination of X-ray crystallography, NMR, and electrochemical techniques. The palladium(0) complexes undergo reactions with aryl iodides to give the palladium(II) complexes [Pd(Ar){R−N(CH2CH2PPh2)2}]+I-, where the rate of oxidative addition was found to be dependent on the nature of the aryl group, as well as the substitution on nitrogen.
