Reactions of tris(2-pyridyl)phosphine oxides with electrophiles: Formation of 5-substituted 2, 2′-bipyridyls

The reaction of tris (2-pyridyl)phosphine oxides with benzeneselenenyl chloride in methanol gave the corresponding 5-phenylseleno-2, 2′-bipyridyls together with a small amount of 2, 2′-bipyridyls. Similarly, the reaction with arenesulfenyl chlorides in aqueous acetonitrile afforded two kinds of coupling products, 5-phenylthio-2, 2′-bipyridyls and 2, 2′-bipyridyls. While in the reaction with arenesulfinyl chlorides in aqueous acetonitrile, four corresponding bipyridyl derivatives, 2, 2′-bipyridyls, 5-aryhhio-2, 2′-bipyridyls, 5-arylsulfinyl-2, 2′-bipyridyls, and 5-arylsulfonyl-2, 2′-bipyridyls, were formed.

New 2,2'-Bipyridine Derivatives and Their Luminescence Properties with Europium(III) and Terbium(III) Ions

Twenty differently substituted 2,2',2",2"'-III and TbIII ions.The relative luminescence yields, excitation maxima, and emission decay constants were determined for the corresponding EuIII and TbIII chelates.The substituents at the bipyridine moiety had a significant effect on the luminescence properties: the best relative luminescence yields R were obtained for ligands with electron-donating substituents (e.g.Me, Ph), electron-withdrawing substituents (e.g.NO2, COOH) had a reverse effect.However, no clear correlation between the relative luminescence yields and the substituent parameters was found.
