Arene Ruthenium Cages: Boxes Full of Surprises

Therrien, Bruno

In: European Journal of Inorganic Chemistry, 2009, vol. 17, p. 2445-2453

Self-assembly of polypyridyl ligands with dinuclear arene ruthenium building blocks bridged by chlorido, oxalato or benzoquinonato ligands has allowed the construction of a wide range of cationic metalla complexes possessing different architectures and functionalities: (i) metalla-rectangles showing host-guest possibilities and allowing intramolecular template-controlled photochemical [2 + 2]...

Artificial metalloenzymes for enantioselective catalysis : the phenomenon of protein accelerated catalysis

We report on the phenomenon of protein-accelerated catalysis in the field of artificial metalloenzymes based on the non-covalent incorporation of biotinylated rhodium–diphosphine complexes in (strept)avidin as host proteins. By incrementally varying the [Rh(COD)(Biot-1)]+ vs. (strept)avidin ratio, we show that the enantiomeric excess of the produced acetamidoalanine decreases slowly....
