The selective oxidation of [(N 4 )Rh I (ethene)] + (N 4 = tetradentate N ligand) results in stable 2‐rhodaoxetanes (Rh III ‐ κ 2 ‐ C , O ‐2‐oxyethyl complexes) that become reactive upon protonation of the 2‐rhodaoxetane oxygen atom (see scheme). Metallaoxetane rearrangement changes from the elimination of acetaldehyde in a non‐coordinating solvent to the formation of a metallacyclic amide in acetonitrile. The observed stoichiometric amidation of coordinated ethene might indicate new possibilities for catalytic formation of C‐N bonds.
