N2 - The synthesis and characterization of several zero-valent cobalt complexes with a bis(olefin)-amino ligand is presented. Some of these complexes proved to be efficient catalysts for the selective oxidation of secondary and allylic phosphanes, as well as diphosphanes, even with a direct P−P bond. With 5 mol % catalyst loadings the oxidations proceed under mild conditions (25–70 °C, 7–22 h, 2 bar N2O) and afford good to excellent yields (65–98 %). In this process, the greenhouse gas N2O is catalytically converted into benign N2and added-value organophosphorus compounds, some of which are difficult to obtain otherwise.
