**The simultaneous migration of two ligands** makes the rearrangement of nitrile oxides __(1)__ to isocyanates __(2)__ one of the most interesting ones in organic chemistry. However, use of the thermal reaction __(1)__ is severely limited by competing dimerization. The rearrangement proceeds in exce
