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 excellent yields with SO 2 as catalyst.
