Description

General description

Iodine monochloride is an interhalogen compound. It forms various complexes with ethyl, isopropyl and t-butylbenzenes. Electrically conducting solution of ICl is obtained on dissolution of ICl in polar solvents. ICl is a green oxidizing agent and participates in the following transformations:

• aldose hemiacetals to the corresponding aldose lactones
• diarylmethanols to the corresponding diarylmethanones
• arylalkylmethanols to the corresponding arylalkylmethanones
• dialkylmethanols to the corresponding dialkylmethanones

Application

Iodine monochloride (ICl) may be employed as a reagent in the following processes:

• Halogenation of methoxy and dimethoxybenzenes
• Synthesis of flavones.
• Preparation of 1-naphthaldehydes.

It may be used as an iodinating agent in the conversion of alkylboranes to alkyl iodides.
