Stabilized 2-Iodoxybenzoic Acid (SIBX)

Since 1994,1 2-iodoxybenzoic acid (IBX) has been well recognized as a very powerful and selective oxidizing agent. Similar to the Dess–Martin periodinane, IBX is an environmentally benign alternative to metal-based oxidizing agents. However, IBX is not often used due to the fact that it is an impact-sensitive explosive material, which prevents its shipping and transport, as well as its application in industry.2 Sigma-Aldrich is pleased to introduce a stabilized formulation of IBX (SIBX) that displays none of the explosive properties of IBX, while maintaining excellent reactivity and selectivity.

SIBX has demonstrated use in the:

  • Oxidation of alcohols to carbonyl compounds.3
  • Oxidative demethylation of 2-methoxyphenols.3
  • Oxidative dearomatization of 2-alkylphenols into orthoquinols (alternative to Barton or Adler oxidations).4
