说明

一般描述

Iodine is a micro nutrient[1] essential for thyroid synthesis.[2] It is a component of Gram′s iodine which has been reported to be used in identifying cellulase-producing microorganisms.[3] Photogeneration of iodine from anatase TiO2 has been studied.[4]
 

应用

Iodine may be used as a promoter during the synthesis of conjugated molecules with benzofulvene core.[5] It may be employed as a TLC stain for detection of perillyl alcohol.[6]
It may be used as a catalyst in the synthesis of the following:
  • Quinoxalines by reacting 1,2-diamines with 1,2-dicarbonyl compounds under microwave condition.[7]
  • N-Substituted pyrroles via condensation of 2,5-dimethoxy tetrahydrofuran with amines under microwave condition.[8]
  • Disulfidation of alkenes.[9]
