Bidentate ligands of the type Mes*PC(R)Py ((E)-2, R = H; (Z)-9, R = SiMe3; Mes* = supermesityl = 2,4,6-tri-tert-butylphenyl; Py = 2-pyridyl) were synthesized. Ligand (E)-2 was synthesized by reacting Mes*P(Li)SiMe2(t-Bu) (4) with 2-pyridinecarboxaldehyde. Ligand (Z)-9 was synthesized via a PdCl2(dppb)-catalyzed coupling reaction between 2-bromopyridine and Mes*PC(SiMe3)M ((E)-7, M = ZnCl; (Z)-8, M
