Novel nitrene precursors of the form PhINSO2R (R = 1-methylimidazolyl (1),
pyridine (2), 2-pyridine N-oxide (3)) have been prepared that contain heter
ocyclic sulfonamide residues. These new iodinanes are evaluated as sources
of the corresponding heterocycle-containing nitrenes in aziridination and s
ulfimidation reactions. (C) 1999 Elsevier Science Ltd. All rights reserved.
