Homogeneous catalytic oxidation of amines and secondary alcohols by molecular oxygen

Ruthenium trichloride catalyses the homogeneous oxidation of secondary alcohols to ketones, primary amines to nitriles, and 2-aminoalkanes to imines by O2; this is the first example of a homogeneous catalytic oxidation of an amino-group.

Oxidation of cyclic ketones by hydrogen peroxide catalysed by Group 6 metal peroxo complexes

Molybdenum peroxo complexes stabilized by picolinato and pyridine 2,6-dicarboxylato ligands catalyse oxidation of cyclic ketones by H2O2 to lactones and their derivatives; this represents a catalytic analogue of the Baeyer–Villiger reaction.

Oxygen transfer from group 8 metal dioxygen complexes. Rhodium(I) catalysed co-oxygenation of terminal olefins with triaryl-phosphine and -arsine ligands

Direct oxygen transfer in the intermediate rhodium dioxygen complex is the preferred mechanism for L3RhCl catalysed co-oxidation of terminal olefins and the ligands L.
