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.
Chelation-assisted electrocyclic reactions of 3-alkenyl-2,2′-bipyridines: an efficient method for the synthesis of 5,6-dihydro-1,10-phenanthroline and 1,10-phenanthroline derivatives
An efficient method for the synthesis of substituted 5,6-dihydro-1,10-phenanthrolines and 1,10-phenanthrolines has been developed by means of the chelation-assisted photochemical electrocyclic reactions of 3-alkenyl-2,2â²-bipyridines.
