An Electrophilic Aromatic Substitution by N-Methoxyamides via Hypervalen Iodine Intermediates
Kikugawa, Yasuo,Kawase, Masami
, p. 581 - 582 (2007/10/02)
Treatment of N-methoxyamides with hypervalent iodine compounds generates electron deficient nitrogen species which react intra- or intermolecularly with an aromatic group to give N-aryl-N-methoxyamides in good yields.
