Palladium(II) and platinum(II)-C-(3)-substituted 2,2 '-bipyridines / Minghetti, G; Doppiu, A; Zucca, A; Stoccoro, Sergio; Cinellu, Maria Agostina; Manassero, M; Sansoni, M.. - In: CHEMISTRY OF HETEROCYCLIC COMPOUNDS. - ISSN 0009-3122. - 8:8(1999), pp. 1127-1137.
Abstract:
Reaction of Pd(OAc)2 with HL I and HL 2 (HLl=6-iso-propyl-2,2"bipyridine; HL2=6-neo-pen~l-2,2 '-
bipyridine), followed by treatment with LiCl or KI, gives [PdCI(Lt)]2, (1), [PdCI(L2)]2 (2), and [PdI(L2)]2
(3), respectively. The chloride bridge in complexes 1 and 2 is split by PPh 3 to give the mononuclear
species PdCI(L I)(PPh3) (4) and PdCI(L')(PPh3) (5). Spectroscopic data provide evidence for coordination
of the deprotonated ligands through a nitrogen and the C~3) atom of the 6-substituted pyridine. An
analogous plat#ram complex PtCI(L3)(SMe2) (6) (HL3=6-tert-bu~l-2,2"bipyridine) was obtained fi'om
trans-PtCIMe(SMe,)2 and HL 3. The ctystal structures of compounds 1 and 6 have been solved by X-ray
diffraction analysis.
