range of bifunctionaloxazolidinenitroxylradicals have been prepared. The application of these co-catalysts to the copper-based aerobicoxidation of alcohols was then investigated. From these studies it was found that the parent tetramethyloxazolidine nitroxylradical L1 was competent for oxidation in the presence of 2,2′-bipyridine, and the bifunctional pyridyl-containing nitroxylradicals L2 and

Sandwich complexes [Re(η6-C6H6)2]+ are versatile scaffolds for conjugating a variety of ligands, as in ferrocene. The high stability of a so-prepared Re/Co system under light irradiation is exemplified with photocatalysis for proton reduction.
