Uranium (II) systems shown to effect reduction of azobenzene to yield a bis(imido) uranium (VI) complex

Chemists have demonstrated that uranium can take part in multi-electron transfer reactions, in the first clear example of a single metal four-electron reduction process involving an element from the f block.
