Hydrogenation, the addition of hydrogen to unsaturated organic compounds, is broadly used in chemical production and usually mediated by precious-metal catalysts. Now, adding to a developing trend to go metal-free, Douglas W. Stephan and colleagues at the University of Windsor, in Ontario, report the first catalysts that eschew costly metals and can use H2 directly to reduce imines, nitriles, and aziridines to primary and secondary amines under . . .
