Complexes with a Pincers. 2,6‐Diphenylpyridine as Twofold‐Deprotonated (C ∧ N ∧ C) terdentate ligand in C,C‐trans‐, and as mono‐deprotonated (C ∧ N) chelate ligand in chiral C,C‐cis‐complexes of platinum(II) and palladium(II). Preliminary communication

Abstract 2,6‐Diphenylpyridine forms, as twofold‐deprotonated, terdentate ligand, complexes with Pt(II) and Pd(II), having two adjacent five‐membered metallocycles. As mono‐deprotonated, bidentate ligand, it forms cis‐bis‐complexes having a chirality axis. Pt(II) complexes undergo thermal and photochemical oxidative addition reactions, yielding stable Pt(IV) compounds. Pd(II) complexes yield substitued 2,6‐diphenylpyridine in photochemical reactions.
