persistent triplet sulfonyl nitrene, FSO(2)N, was produced in the gas phase in high yields (up to 66%) by flash vacuum pyrolysis of FSO(2)N(3). Surprisingly, no rearrangement of FSO(2)N was observed, but the long-sought radical FSO(2) (22%) and traces of SO(2) (3%) were identified by IR ((15)N, (18)O, (34)S) spectroscopy. The photoinduced Curtius rearrangement of the nitrene to FNSO(2) was observed in
