The rhodium peroxido complex 1, which can be prepared from 2 and dioxygen, participates in mono‐oxygenation of a phosphine and dioxygenation of tetrakis(dimethylamino)ethylene to give, respectively, phosphine oxide and a urea derivative, while peroxygenation of 9,10‐dimethylanthracene to yield the anthracene endoperoxide takes place in the presence of dioxygen and substoichiometric amounts of 1 (see
