IMIDAZOLIUM DICHROMATE Chemical Properties,Usage,Production

Chemical Properties

ORANGE-BROWN CRYSTALLINE POWDER

Uses

A mild selective reagent for the oxidation of allylic and benzylic alcohols to the corresponding carbonyl compounds.

Preparation

Imidazolium dichromate is easily prepared by the addition of Imidazole to a solution of an equimolar amount of Chromium(VI) Oxide in a minimum amount of water.

reaction suitability

reagent type: oxidant

storage

All chromium(VI) reagents must be handled with care. The mutagenicity of chromium(VI) compounds is well documented. This reagent should be handled in a fume hood.
