The intermediates allow the facile introduction of cyano groups, which are converted into amino diacetic acid moieties. Together with the terpyridine nitrogen atoms they shield coordinated europium(III) ions completely from the solvent. The terpyridines may be further functionalized for specific applications using ligands, bromo substituents, and standard transition metal mediated coupling methods.

The approach allows flexible construction of chromophore and coordination sphere with control of photophysical properties. Europium (III) complexes [Eu1]-[Eu5] prepared in this way exhibit intense long-life metal-centered luminescence in aqueous media. The aromatic substituent in the position 5 of bipyridine has a significant influence on luminescence parameters and is used to introduce functionality for bioconjugation.

The adsorption of starting benzaldehydes and ethyl acetoacetate on the surface of copper and aluminum nanooxides resulted in the activation of these molecules and accelerated the Hantzsch reaction. In addition, considerable activation of ammonia and intermediates (chalcone and enamine) on the surface of aluminum nanooxide facilitated an increase in the rate and selectivity of the process.

The corresponding enantiomerically enriched sulfoxides with up to 78% enantiomeric excess are prepared by the asymmetric oxidation of sulfides using a modified Sharpless method. The yield of sulfoxides is shown to decrease with an increase in the bulk of the aliphatic group and with a decrease of the inductive effect of the hydrocarbonic moiety on the sulfur atom.????Supplemental materials are available for this article.
