Huo, Jianqiang published the artcileFacile synthesis and platinum complexes of 4′,5,5”-trisubstituted-2,2′:6′,2”-terpyridines, SDS of cas: 27943-46-0, the publication is Dalton Transactions (2011), 40(29), 7534-7540, database is CAplus and MEDLINE.
The synthesis of trisubstituted 4′,5,5” terpyridines is described. The strategy begins with synthesis of 2-acetyl-5-bromopyridine (3) from 2,5-dibromopyridine, substitution of the bromine in 3 using a variety of metal-catalyzed reactions and then formation of the terpyridine using the Krohnke reaction. The complexes were prepared by reaction of [Pt(PhCN)2Cl2] with the appropriate Ag salt followed by addition of the terpyridyl ligand. The crystal structure of two complexes were determined via x-ray diffraction and the MLCT (metal-to-ligand charge-transfer) emissions determined by UV/visible spectroscopy.
